The Communicator's Mindset: Audience, Message, Medium

Presentation track, branch pr-foundations (Foundations) · Node PR0.01 · ~5 focused hours · Mastery gate ≥ 85%

A founder builds a forty-slide deck for her board over eleven hours. The board gives it nineteen minutes. Eleven of those nineteen go to slide 6, a chart she assembled in four minutes because the section looked thin. Nothing on the other thirty-nine slides changes a single thing anyone does on Monday.

That is not a design failure. Every slide was aligned, the fonts matched, the logo sat in the same corner throughout. It is a failure that happened before the software opened, in the ninety seconds when she should have asked who is in the room, what they are deciding, and what one sentence would decide it. She skipped those ninety seconds and paid for them with eleven hours.

The whole Presentation track is built on a claim you can test against your own experience: the quality of a deck is set almost entirely by decisions taken before any slide exists, and the decisions taken inside the tool mostly determine whether that earlier thinking survives contact with a reader. Sixteen hours is a realistic build for a twelve-slide decision deck. Eight of those sixteen come before the first slide is created, and the split is not an accident of how slow people are at PowerPoint. It is where the difficulty actually lives.

So the first thing taught here is not a tool. It is a sequence: takeaway, audience, decision, medium, and only then artefact. Every later branch assumes you have run that sequence. The mechanics branch teaches you to build what the sequence chose. The chart-craft branch teaches you to draw the evidence it demands. The storytelling branch teaches you to order the claims it produced. None of them can rescue a deck that started with the wrong takeaway, because there is no arrangement of slides that answers a question nobody asked.

There is a limit to what can be taught here, and stating it now saves a lot of disappointment later. Taste does not come from a module. It comes from reps, from feedback that stings, and from having seen four hundred decks. What can be taught is grammar: the rules that separate a chart that reads from one that does not, the structures that make an argument follow, the checks a machine can run on a slide before a human wastes attention on it. Grammar is not style, and knowing it will not make you interesting. It will make you correct, which is the part that is teachable and the part that most working analysts are missing.

One more thing about the shape of what follows. The exercises in this track are graded twice, once by a machine and once by you against a rubric you cannot see until you have committed your own score. The machine checks seven rules on a slide: alignment, one message, chart choice, the title stating the message, colour discipline, declutter, and hierarchy. It is a floor. A slide can pass all seven and still say nothing worth saying, which is why the rubric exists and why the two scores are blended rather than one replacing the other.

Learning objectives

You can:

1. Write a one-sentence takeaway for any piece of analysis before opening any tool, and test it against three properties: it is a claim, it is falsifiable by the data you hold, and it names or implies the action it supports.
2. Build an audience profile on three axes (what they already know, what they are deciding, what they are afraid of), and show how a change on any one axis changes the takeaway.
3. Find the decision a communication exists to serve when the requester has not stated one, using the four questions that recover it, and state what to do when the honest answer is that no decision is pending.
4. Choose a medium on purpose from the six standard forms, pricing each in reader-minutes for a stated audience size, and justify the choice against exactly one rejected alternative.
5. Distinguish a reading deck from a presented deck, size each correctly in words per slide, and compute the attention cost of the hybrid that tries to be both.
6. State what a slide is: one claim with the evidence that supports it, and apply that test to reject slides that are containers for what you know.
7. Apply the seven machine-checkable rules as a floor, compute a blended machine-plus-rubric score, and say what the machine cannot see.
8. Budget the hours for a deck of a stated size, name where they go, and defend the share that is spent before any slide exists.
9. Diagnose the three arrival failure modes (the data dump, the beautiful empty deck, and the deck that answers a question nobody asked) from symptoms, and name the repair each one needs.
10. Ask for feedback in a form that produces useful answers, and triage a redline into substance, structure and style so the expensive fixes happen first.

Prerequisites & connections

Builds on. Nothing. This is a day-one entry point, and it assumes no software, no prior deck and no finance beyond arithmetic. If you have already worked through M8.02 (the business teardown) or any of the CN case modules, you will have an analysis of your own to use for the mini-project, which makes the hour worth more; if you have not, the project supplies a fallback brief.

Feeds forward. PR0.02 takes the artefact choice you make here and teaches the tool that builds it, stopping at using a template rather than authoring one. PR2.01 owns chart-form choice in full; the compact grammar table below exists only so the worked examples can name a chart correctly, and it is deliberately shallow. PR4.01 and PR4.02 own the executive storyline and title logic across a whole deck, taking the single takeaway written here and turning it into an ordered argument. PR5.01 to PR5.03 own the archetypes (the consulting deck, the board deck, the research report) that the medium choice here points at. PR6.01 owns delivery and Q&A. PR7.01 is the capstone that runs the whole sequence end to end.

Six neighbours own material that touches this one, and the non-overlaps are deliberate rather than accidental. None of their material is rebuilt here. M10.03 owns the analyst's written deliverables: the one-page memo, the longer research report, the exhibit-design drill and the action-title convention as applied to written work; what is owned here is the choice that precedes all of them, which is whether a memo is the right artefact at all. CN1.03 owns answer-first synthesis, the governing thought, the pyramid and the so-what ladder; the single takeaway taught here is the input that synthesis produces, and the consulting module's own hand-off note draws the boundary from the other side.

The craft neighbours divide the same way. CN1.02 owns hypothesis-driven problem solving and the ghost deck as a consulting artefact, while PR3.02 owns the ghost deck as a build technique. PR2.02 owns decluttering and colour as data-visualisation craft, and PR1.02 owns alignment, grids and type. Where a section below names one of those ideas, it names it and moves on rather than teaching it.

1. The one-sentence takeaway, written before any tool opens

Open a blank document, not a blank deck, and write one sentence that a reader could disagree with. That sentence is the takeaway, and until it exists there is nothing to build.

Three properties separate a takeaway from a topic. It is a claim, meaning someone could hold the opposite view and be wrong. It is falsifiable by the data you actually hold, meaning you can point at the numbers that would break it. And it names or implies an action, meaning a reader who accepts it knows what changes.

Run those tests on four sentences about the same quarter at Chandra Naturals, a synthetic Indian personal-care brand whose numbers carry most of the examples here.

The fourth sentence is longer than the others and that is fine. Length is not the test. The test is whether a board member who reads it knows what she is being asked to agree to, and whether she could argue against it using the same numbers.

Notice what the fourth sentence costs you. It commits. "Growth is strong but cash is tight" survives any outcome, which is exactly why it is worthless: a sentence that cannot be wrong cannot be useful either. The moment you write November rather than February, you have exposed a claim to attack, and the attack is the point. If the board disagrees, you have found the real conversation in the first minute instead of the fortieth.

A working rule, and it is the one habit from this section worth installing permanently: if you cannot write the takeaway, you are not ready to build. Sometimes that means the analysis is unfinished. More often it means the analysis is finished and you have not yet decided what it means, which is a different problem with a faster fix. Sit with the numbers and ask what you would tell a colleague in a corridor if you had eleven seconds. Whatever comes out of your mouth is close to the takeaway, and it is almost always sharper than what comes out of your keyboard.

Revise the sentence last, as well as writing it first. When the analysis moves, the sentence moves, and every slide built on the old sentence is now wrong in a way that alignment cannot fix. Analysts who build first and write the takeaway last discover this at eleven at night.

2. Audience: what they know, what they decide, what they fear

An audience profile is three lines long. Any longer and you are writing a persona document instead of preparing a communication.

What they already know sets your floor. It determines the vocabulary you may use without definition, the context you may skip, and the caveats you must state because this reader will not supply them from memory. Guess low on knowledge of your specific analysis and guess high on general competence. A board director who has run three companies does not need "EBITDA" defined and does not know why your gross margin moved 4.5 points.

What they are deciding sets your target. Everything in the artefact either moves that decision or is decoration, and the decoration is not neutral because it costs attention that the decision needed. This is the axis most often left blank, and section 3 is entirely about recovering it when nobody states it.

What they are afraid of sets your order. Every reader carries an unstated worry, and if your communication does not reach it, they will spend the meeting reaching for it themselves. A bank's relationship manager fears a covenant breach discovered by an auditor rather than by him. A board fears being asked for money at short notice. A founder fears a spending decision that cannot be reversed. Name the fear and address it early, and the room settles; leave it unaddressed and every question drifts back toward it.

The same quarter at Chandra Naturals produces three different takeaways once those three lines are filled in, and the differences are not cosmetic.

Same company, same quarter, same underlying data set, and three sentences that share not one number. That is what an audience profile is for. It is not a courtesy to the reader. It is the mechanism that selects which of your forty facts are relevant, and without it the selection defaults to "all of them", which is the data dump.

One warning about adapting to an audience, because it is easy to take too far. You change the framing, the depth and the vocabulary. You never change the substance. The bank gets a different sentence from the board because it is deciding something different, not because it is entitled to a rosier version of the same facts. Runway of 7.4 months is 7.4 months in every room, and if the bank asks, it hears 7.4. An adapted message and a managed message look similar from outside and are opposite things.

3. Finding the decision when nobody states it

Most requests arrive without a decision attached. "Can you put something together on our pricing for Thursday?" contains no decision, no audience and no scope, and the analyst who starts building from it will produce twenty-two slides of competitor price tables that answer nothing.

Four questions recover the decision, and they are asked of the requester, not of yourself.

The first is what happens after Thursday. If the honest answer is "we discuss it", ask what would have to be true to stop discussing it. Discussion is not a decision, but it usually sits next to one.

The second is who else is in the room. The requester is rarely the decider. Knowing that the sales head will be present, and that she owns the April price list, converts a vague pricing question into a specific one about the April price list.

The third is what would change your mind. This is the sharpest of the four because it forces the requester to name the evidence that matters, which is the evidence you should be building. If the answer is "nothing", you have learned that the decision is already made and you are being asked for justification, which is a different job that you should do knowingly or decline.

The fourth is what happens if we do nothing. The status quo is always an option and is usually the default outcome, so knowing its cost tells you how large your recommendation has to be to be worth the disruption.

Run those four on the pricing request and it collapses into something buildable. The decision is whether to move the 200 ml face wash from ₹349 to ₹399 in the April price list. The decider is the sales head. What would change her mind is evidence about volume loss, and doing nothing costs the margin that a 14.3% price rise would have earned. That is a one-page analysis rather than a twenty-two-slide deck, and the fifth worked example builds it.

Sometimes the four questions return an uncomfortable answer: no decision is pending. That happens more often than anyone admits, and the professional response is to say so before building. A status update with no decision attached is an information transfer, and information transfers belong in writing, cheaply. The failure is not that no decision exists. The failure is spending eleven hours as though one did.

There is a variant worth naming because it is common in consulting and in equity research. The requester genuinely does not know what they are deciding, and your first contribution is to tell them. "Here are the three decisions this analysis could support; which one are we actually facing?" is a better opening than any deck, and it takes one email.

4. Medium on purpose, priced in reader-minutes

Six forms carry almost all analytical communication, and each has a cost to the reader that you can compute before choosing. Reading runs at roughly 200 to 240 words a minute for ordinary business prose; 220 is the figure used throughout this track. Speaking runs at about 130. Those two rates do most of the work.

The column that matters is the last one. A presented deck costs nearly forty-nine times what an email costs, measured in the only currency your audience actually spends. That does not make the presented deck wrong. It makes it expensive, and expensive things need a reason.

The reason is almost always one of three. You need the room, because the decision requires several people to hear the same thing at the same time and commit in front of each other. You need the argument, because the case is long enough that a reader left alone would stop halfway. Or you need the questions, because you cannot anticipate the objections and need to handle them live. If none of those three applies, the meeting is a habit.

Notice what the table does not say. It does not say shorter is better. A two-page memo that takes five minutes and lands is worth more than an email that takes fifty seconds and gets misread, and the analyst who compresses a genuinely complex argument into 180 words has not saved anyone time. The cost figure is one input to a judgement, not the judgement.

The choice is also reversible in one direction only. An email can escalate into a meeting when someone asks a question you cannot answer in writing. A meeting cannot be un-held. Default to the cheaper medium, and let the audience pull you upward.

5. The reading deck and the presented deck, and why one artefact cannot be both

A slide has two possible jobs and they pull in opposite directions.

A presented deck supports a speaker. The audience is listening, so the slide carries the minimum that a listener needs to follow: an action title, one exhibit, a handful of labels. Thirty words is generous. Everything else is in the speaker's mouth and in the notes.

A reading deck is a document with a deck's page shape. Nobody is speaking, so the slide carries the whole argument in text: three hundred words is normal, and the reader controls the pace. It circulates in advance, it survives forwarding, and it is read alone.

The hybrid tries to serve both and fails at a rate you can compute. Put 180 words on a slide and stand in front of it. Your audience reads those words silently at 220 words a minute, finishing in 49 seconds. You say them aloud at 130 words a minute, finishing in 83 seconds. For 34 seconds of every 83, which is 41% of the time you are speaking, your audience has finished the slide and is waiting for you, reading ahead, or checking mail. Across fourteen such slides, the deck takes 19.4 minutes to say and 11.5 minutes to read, and the audience spends the difference somewhere other than with you.

That arithmetic is the whole argument against the dense presented slide, and it is worth carrying because it converts a matter of taste into a matter of seconds. The room is not bored because your slides are ugly. The room is bored because it finished reading before you finished talking, every single slide, for forty minutes.

The practical consequence is that a serious deck is often two artefacts. The board pack that circulates 48 hours ahead is nine pages of 340 words, 3,060 words in total, read in about 14 minutes by anyone who chooses to. The version shown in the room is fourteen slides at about 31 words each, 434 words on screen against roughly 3,900 spoken in a thirty-minute slot, which puts about 11% of what is said in front of the eye and the rest in the ear. Building both costs more than building one. Building one that does both costs your audience's attention, which is a bill you never see itemised.

There is a third artefact people forget: the deck after the meeting, forwarded to someone who was not there. A presented deck fails that reader completely, because the speaker is missing and the slides were built assuming a speaker. Either send the reading version, or write speaker notes dense enough that the slide plus its notes reconstruct the argument. Deciding which, in advance, is part of choosing the medium.

6. What a slide is

A slide is one claim with the evidence that supports it. Nothing else belongs in the definition, and almost every bad slide violates it in the same way, by being a container for what the author knows about a topic rather than an argument about it.

The test takes four seconds. Read the title. If the title is a noun phrase, the slide is a container. If the title is a sentence with a verb that could be contradicted, the slide is an argument, and the body's only job is to make the title believable.

The right column takes longer to write, and that is the cost being paid deliberately. Writing "Revenue by state" requires knowing what data is on the slide. Writing "Three states now carry 71% of revenue, up 13.1 points in two years" requires knowing what the data means, having computed the 71.0% and the 13.1 points, and being willing to be wrong about both. The title is where the thinking is, which is why the title-is-the-message rule is one of the seven the machine checks.

Two consequences follow, and both are unpopular.

The first is that a slide with two claims is two slides. When a title needs an "and" joining unrelated assertions, split it. The exception is a genuine compound claim where the second half is the consequence of the first, as in the gross-margin example above, where the 53.7% follows from the 4.5 points.

The second is that a slide with no claim is not a slide. Agenda pages, section dividers and the "any questions" closer are navigation furniture, and they are fine as furniture. What is not fine is the slide that presents four charts under the title "Market overview" because the author gathered four charts. If none of them makes a claim, none of them belongs, and the honest version of that slide is a sentence in an email.

The compact chart grammar below exists so the worked examples can name a form correctly. The chart-craft branch owns the full treatment, including the cases where these rules bend.

Four rules sit on top of the table and hold everywhere. One message per chart. The title states the message. Colour carries meaning or is neutral. Declutter before decorating. And a fifth that decides more charts than the rest combined: sort by value unless the order is intrinsic, because a category order is a claim about what matters, and alphabetical is a claim that nothing does.

Three forms are simply out. Dual axes, because the reader cannot tell which axis a line belongs to and the author chose the scaling that makes the story look how they wanted. Three-dimensional effects, because they add ink that encodes nothing and distort the very comparison the chart exists to make. And the pie chart above three slices, because human eyes compare angles badly: in the Chandra Naturals state mix, the two smallest FY26 slices differ by 5.82 degrees out of 360, a difference no reader will see and every bar chart makes obvious.

7. What is teachable here, and what is not

Two things get confused constantly, and separating them tells you what to expect from the next seven branches.

Taste is the ability to look at a slide and know it is wrong before you can say why. It comes from volume and from feedback: hundreds of decks built, shown, criticised and rebuilt. No module produces it. What a module can do is shorten the loop, by giving you rules that catch the common errors so your feedback is spent on the interesting ones.

Grammar is the set of rules that are stable, checkable and worth memorising. A bar chart sorted by value reads faster than one sorted alphabetically. A title that states a claim is more useful than a title that states a topic. Two series on different units do not go on two axes. None of that is a matter of opinion, and all of it can be tested against a slide by a person or by a machine.

The track teaches grammar and creates the conditions for taste. That division is honest about the limits, and it also sets your expectations correctly about the exercises. When a drill marks your chart choice wrong, it is applying a rule, and the rule is defensible. When your rubric self-score disagrees with the machine on whether a slide has one message, the disagreement is the lesson, because that is precisely the judgement the machine cannot make and you must.

An analogy that holds well enough to be worth the sentence: grammar in language does not make you a writer, and its absence guarantees you are not one. You can be grammatical and dull. You cannot be ungrammatical and trusted.

8. The seven-rule floor, and what a machine cannot see

Every exercise in this track is scored twice. A machine runs seven rules against your slide. You separately score yourself against a rubric, and the rubric stays hidden until your self-score is committed, which is the write-before-peek convention used everywhere in the programme.

The seven rules are these. Alignment: every element sits on a shared edge or a grid column, with no orphan positioned by eye. One message: the slide makes exactly one claim. Chart choice: the form matches the message type, per the grammar table. Title is the message: the title is a sentence with a verb, not a noun phrase. Colour discipline: colour encodes something, or it is neutral, with one accent at most. Declutter: no element that encodes nothing survives. Hierarchy: size, weight and spacing put the most important thing first in the reading order.

The two scores blend at 0.6 machine and 0.4 rubric, and the pass mark is 0.80, rising to 0.90 for the crown nodes and the capstone. Work an example. A slide that scores 0.86 on the machine and 0.72 on your rubric blends to 0.804, which passes the ordinary gate and fails a crown by a wide margin. A slide at 0.95 machine and 0.60 rubric blends to 0.810, barely better, which tells you something about the weighting: a technically clean slide with a weak argument does not buy its way through. Working the other direction, a rubric score of 0.70 needs a machine score of 0.867 to reach 0.80 at all.

What the machine cannot see is the part that decides whether the deck was worth building. It cannot tell whether the claim in your title is true. It cannot tell whether the decision you targeted is the decision that was pending. It cannot tell whether the chart's message is the message that matters, only that the chart's form fits the message you declared. A slide can pass all seven rules and be a beautifully rendered answer to a question nobody asked, which is why the rubric carries 40% and why every exercise asks you to state the decision before you build.

Treat the seven as a floor in the strict sense. Falling below them is a defect you should never ship. Clearing them is not an achievement, and a deck that clears them and changes nothing has still failed.

9. Where the hours actually go

Ask someone how long a deck takes and they will estimate the time spent in the software. That is the smallest piece.

Here is a realistic budget for a twelve-slide decision deck built once, on analysis you already hold.

Half the time goes before a slide exists. About a third goes inside the tool, and that third is the part every beginner budgets for and the only part most people count. The last sixth, rehearsal and revision, is the part that gets cut when the deadline moves, and cutting it is why so many decks are shown for the first time to the audience that matters.

Two practical implications. First, if you are three hours from a deadline with no takeaway written, you are not three hours from a deck, you are three hours from a bad one, and the correct move is to buy time or to switch to a cheaper medium. Second, the data-checking hours are not compressible in the way the building hours are. A wrong number on a beautiful slide destroys the whole artefact, and the recovery cost is not four hours of rebuilding, it is the next three months of everything you present being checked twice.

The numbers above scale roughly linearly in slides for small decks and worse than linearly for large ones, because a thirty-slide deck has an ordering problem a twelve-slide deck does not. That is one of several reasons the archetype templates later in the track are sized where they are.

10. The three failure modes you arrive with

Almost every learner shows up with one of three habits, and naming yours saves a branch of frustration.

The data dump is the most common and the easiest to diagnose. The deck contains everything the author found, in the order they found it, because leaving something out felt like hiding it. A real example of the shape: 34 slides and 41 charts booked into a 30-minute slot, which is 53 seconds a slide and 44 seconds a chart. An audience carries about three claims out of a room. Forty-one charts for three surviving claims is 13.7 charts per claim, and thirty-eight of them were work that the audience will never use.

The repair is not "cut slides", because the author does not know which to cut. The repair is upstream: write the takeaway, then keep only what makes the takeaway believable, and put the rest in an appendix where it costs nothing and answers questions if they come. The instinct that leaving things out is dishonest is worth respecting and worth redirecting: an appendix is how you honour it without spending the room's attention.

The beautiful empty deck is rarer and more dangerous, because it survives review. Fonts consistent, everything aligned, a considered colour palette, an icon set, and not one slide that makes a claim. It usually happens when someone learns mechanics before message, which is exactly the order most training uses and exactly the order this track inverts. The diagnostic is the title stack: read only the titles, in order, and see whether they form an argument. If they read as a table of contents, the deck is empty however good it looks.

The deck that answers a question nobody asked is the most expensive of the three, because all the work is real and all of it is wasted. It is the direct output of skipping section 3. The symptom in the room is a first question that starts "this is helpful, but what we actually need to know is". The repair is upstream of everything, in the four questions, and the cost of skipping them is roughly the whole build: 22 hours of build plus a 60-minute meeting for seven people is 29 person-hours, of which the two slides that touched the real question are 7.7% of a 26-slide deck.

You probably have one of the three. Data dumpers are usually analysts with genuine depth who are afraid of being caught not knowing something. Empty-deck builders are usually people with design instincts and no ownership of the argument. Wrong-question builders are usually eager and under-briefed, and they are the easiest to fix, because the fix is a conversation before the work rather than a habit change during it.

11. Feedback: asking for it, and taking a redline

Feedback that arrives as "looks good" is worth nothing and is your fault, not the reviewer's. The question you asked produced it.

Ask for feedback on a named axis and at a named stage. Three questions that reliably produce useful answers: "Read only the titles and tell me whether the argument follows." "Which slide would you cut if you had to cut one?" "What will the first question in the room be?" Each one is answerable in under a minute, each targets a specific failure, and none of them can be answered with "looks good".

Timing matters as much as phrasing. Show the titles-only storyline before you build anything, because that is when structural feedback is cheap. Show the built deck when you want to know whether it reads. Asking for structural feedback on a finished deck puts the reviewer in an awkward position and puts you in a worse one, because you now have to choose between rebuilding and defending work you know is wrong.

Receiving a redline is a separate skill. Comments arrive mixed, and the order you fix them in decides whether you finish. Sort every comment into three tiers.

Substance comments say a claim is wrong, unsupported, or overstated. These are expensive and they come first, because a structural or stylistic fix applied to a wrong claim is wasted twice.

Structure comments say the order is wrong, a slide is missing, or two slides are one. These come second, and they often dissolve after the substance fixes, because a corrected claim frequently changes what belongs where.

Style comments say the font is inconsistent, the chart is cluttered, the title is a label. These come last. They are also the ones that arrive in the largest number, which is why an untriaged redline feels overwhelming: five comments might be two substance, one structure and two style, and it is the two substance comments that carry all the work.

One rule about disagreement, and it is worth holding to. You may reject a comment. You may not reject it silently. Reply with the reason, once, and if the reviewer holds their position after that, they are probably seeing something you are not, because they have the reader's view and you have the author's.

12. The placement diagnostic, and how to skip ahead

The diagnostic is twenty items in four clusters of five. The clusters are message and audience, tool mechanics, chart grammar, and storyline structure, which map onto the branch groups you will meet.

Each item is 5% of the whole and 20% of its cluster. Four correct out of five in a cluster, which is 80%, recommends starting that branch at its second node rather than its first, and the recommendation is advisory rather than a gate. The reason it is advisory is that the branches are sequential chains: skipping the first node of the mechanics branch means the second node assumes tool habits you may have from elsewhere, and it is your judgement whether you actually have them.

Two cautions about skipping. A high score on chart grammar usually reflects reading rather than practice, and reading about chart choice and choosing correctly under time pressure are different skills that the drills separate quickly. And a high score on tool mechanics is the least predictive of the four, because knowing where a menu item lives is not the same as having the keyboard habits that make a rebuild cheap.

The diagnostic exists to save you hours, not to rank you. If a cluster comes back at 40%, that is a branch worth its full time, and the honest reading of a low score is that the material is new rather than that you are slow.

13. Where the assistants help here, and where they are dangerous

An assistant is very good at some parts of this sequence and actively harmful at others, and the split is sharp enough to state as a rule.

It is genuinely useful for phrasing. Give it your takeaway and ask for six alternative wordings, and two of them will be sharper than yours. It is useful for the missing-question check: paste your title stack and ask what a sceptical reader would ask that the stack does not answer. It is useful for compression, turning a rambling paragraph into a slide's worth of words without losing a figure, provided you check the figures afterwards.

It is dangerous in three specific places. It will invent a decision when you have not found one, producing a confident recommendation that fits the data and serves no actual choice, which is the wrong-question failure mode arriving faster than before. It will state numbers with false precision, because a plausible number and a correct number look identical in fluent prose. And it will produce a chart choice that matches the words you used rather than the message your data supports, which is a subtle failure that passes a casual read.

The rule that covers all three: an assistant may propose, and it may never decide. The takeaway is yours because you are the one who will defend it. The numbers are yours because you computed them. The decision the communication serves is yours because you asked the four questions and got answers from a person.

``ai-augment-json { "skill": "Pressure-testing a one-sentence takeaway and an audience profile before any slide is built", "use": "After you have written your own takeaway and filled in the three audience lines by hand, paste both into a chat assistant and ask it to attack them: name what the sentence claims, what evidence would falsify it, what action it implies, and which of the three audience lines is doing no work.

Common mistakes & how experts think differently

1. Opening the software first. Tempting because a blank slide feels like progress and a blank document feels like work. The expert writes the takeaway in a text file, then the titles, then opens the tool with the argument already settled. Half the hours in a deck are spent before the tool opens, and the people who look fastest at building are usually the ones who did that half properly.

1. Treating the request as the brief. "Put something together on pricing" is a request. The brief is the decision, the decider and the evidence that would change her mind, and none of the three is in the request. Novices build from requests and are surprised by the first question. Experts spend one email recovering the brief and treat that email as billable work, because it is.

1. Confusing a fact with a takeaway. "Revenue grew 42.6%" cannot be disagreed with, so it cannot be argued for, so it cannot organise a deck. The expert's tell is the "so what" reflex: every fact gets one more sentence beginning "which means", and the deck is built from the second sentences.

1. Adapting substance to the audience rather than framing. The bank hears a different sentence from the board because it is deciding something different. It does not hear a different runway. Analysts who blur that distinction lose the ability to be believed by anyone, and the loss is permanent in a way that a bad chart is not.

1. Building one artefact for two jobs. The dense slide that a speaker reads aloud is the commonest single defect in corporate decks, and its cost is measurable: at 180 words a slide the audience finishes 34 seconds before the speaker, 41% of every slide. Experts build the reading version and the presented version, or they pick one job and accept that the other reader is not served.

1. Leaving the title as a noun phrase. "Revenue by state" is a filing label. It is faster to write, it is never wrong, and it does no work. The expert writes the title first, before the chart, and treats a title they cannot write as evidence that the analysis underneath is not finished.

1. Confusing a full deck with a thorough one. Thirty-eight of forty-one charts are not thoroughness, they are an unwillingness to choose. The expert puts the unchosen material in an appendix, which preserves everything and costs the audience nothing, and then answers the one question that reaches for it with a page number.

1. Asking for feedback with an open question. "What do you think?" gets "looks good", and then the real objection arrives in the meeting from someone senior. The expert asks a closed question at the stage where the answer is cheapest, usually "read only the titles and tell me whether the argument follows", asked before a single chart exists.

1. Fixing style comments first. They are the most numerous and the least expensive, so clearing them feels productive. It is the wrong order: a substance correction frequently deletes the slide whose font you just fixed. Experts triage the redline into substance, structure and style, and work strictly in that order even when the style fixes would take four minutes.

1. Believing the machine score is the standard. Seven rules passed is a floor. Nothing in the seven asks whether the claim is true or whether anyone needed it. The expert reads a clean score as permission to start the real review, not as the review's result.

Worked examples

Every figure below comes from the same computation, and the Verify block at the end of this section restates each one at full precision. All companies are synthetic composites.

Worked example 1: One quarter, three audiences, three artefacts (India, ₹)

The setting. Chandra Naturals (synthetic) sells personal care direct to consumers and through retail. The quarter ended 30 September 2026 produced revenue of ₹18.40 crore against ₹12.90 crore a year earlier and ₹16.00 crore in the previous quarter, at a gross margin of 62.5% against 58.0% a year earlier. Marketing was ₹6.20 crore, other operating costs ₹6.90 crore, working capital absorbed ₹1.90 crore and capital spending was ₹0.40 crore. Cash at quarter end was ₹9.60 crore. The working-capital facility is ₹8.00 crore sanctioned, ₹6.90 crore drawn.

The rest of the inputs the three audiences will ask for, stated once. Prospecting is 72% of marketing spend in both quarters, and marketing was ₹5.10 crore in the previous quarter; new customers were 41,500 this quarter against 39,800 last. Trade receivables stand at ₹9.40 crore against ₹8.69 crore a year earlier, in a 92-day quarter. For the facility, eligible inventory is ₹8.20 crore, eligible book debts ₹6.40 crore of the ₹9.40 crore total, creditors ₹4.10 crore, and the bank's margin is 25%; current assets are ₹27.30 crore against current liabilities of ₹13.40 crore, and the covenant is a current ratio of 1.25.

Three people want the quarter. Same data, three different jobs.

The wrong version. One deck, twenty-six slides, titled "Q2 FY27 Business Review", shown to all three audiences in three meetings across nine days. Slides 1 to 8 are revenue cuts by channel, state, product and month. Slides 9 to 14 are marketing metrics. Slides 15 to 19 are the profit and loss. Slides 20 to 24 are working capital. Slide 25 is "Key Risks", six bullets. Slide 26 is "Thank You". The founder's meeting spends its time on slide 11. The board's meeting spends its time asking what the cash position implies. The bank's relationship manager asks for the receivables ageing, which is not in the deck.

The defect is not the twenty-six slides. It is that no audience profile was written, so the deck was built for the union of three audiences, which is an audience that does not exist.

The corrected version. Three profiles, three takeaways, three artefacts.

The arithmetic behind each takeaway, in order. Revenue growth is 18.40 / 12.90 − 1 = 42.6357%. Gross profit is 18.40 × 0.625 = ₹11.5000 crore against 12.90 × 0.580 = ₹7.4820 crore a year earlier, so gross profit grew 53.7022% on 42.6357% revenue growth, and the gap is the 4.5 margin points. EBITDA is 11.5000 − 6.20 − 6.90 = −₹1.6000 crore; adding the ₹1.90 crore of working capital and ₹0.40 crore of capital spending gives a quarterly cash burn of ₹3.9000 crore, or ₹1.3000 crore a month, so 9.60 / 1.30 = 7.3846 months of runway. Acquisition cost is prospecting spend over new customers: 6.20 × 0.72 × 10,000,000 / 41,500 = ₹1,075.66 this quarter against 5.10 × 0.72 × 10,000,000 / 39,800 = ₹922.61 last, a rise of 16.5887%. Receivable days are 9.40 / 18.40 × 92 = 47.0000 against 8.69 / 12.90 × 92 = 61.9752 a year ago. Drawing power is (8.20 + 6.40 − 4.10) × 0.75 = ₹7.8750 crore, which exceeds the ₹6.90 crore drawn by ₹0.9750 crore. The current ratio is 27.30 / 13.40 = 2.0373.

Notice the mediums. The founder gets a conversation because the decision is small, reversible and needs one question answered in real time. The board gets a reading deck because five people need the same facts before the meeting and the argument is long enough that a listener would lose it. The bank gets a letter because a credit file is a written record and a deck is not a document a credit committee can file. The medium changed twice across three audiences, and each change was forced by the decision rather than by preference.

The checklist to apply. Run it before building any of the three.

1. The takeaway is a claim someone could dispute.
2. The decision is named, in the reader's own terms.
3. Every exhibit carried moves that decision.
4. The medium is the cheapest one that does the job, priced in reader-minutes.
5. The substance matches across all three artefacts, with only framing and depth changing.

Worked example 2: The status deck that should have been an email (US, $)

The setting. Meridian Health Partners (synthetic) is running a twelve-week revenue-cycle improvement project for a hospital system. The team ships a fifteen-slide status deck every Friday into a 45-minute call with nine attendees. Preparing it takes 3.5 hours a week.

The message that actually exists each week. Three things: whether the project is on schedule, what one decision the sponsor owes the team, and what one risk has changed. Everything else is history the attendees lived through.

Here is the wrong version, slide by slide, with the reason each one goes.

Fourteen of fifteen slides are cut, and the surviving one is slide 14.

The corrected version. An email of 168 words, sent Friday morning, with the deck's remaining content as an attached one-page log for anyone who wants it. The weekly call is kept once a month rather than once a week, for the conversations that genuinely need a room.

The email's shape is fixed each week. The subject line carries the schedule status and the decision owed. The first line states the decision and the date it is needed by. The second paragraph is the one changed risk with its new mitigation, and the third is a single sentence on schedule with the variance in days. A closing line offers a fifteen-minute call to anyone who wants one.

The cost, computed. The meeting costs 45 / 60 × 9 = 6.7500 person-hours a week, which is 81.0000 person-hours across twelve weeks, plus 42.0000 hours of preparation, for 123.0000 person-hours in total. At a stated planning rate of $95 an hour that is $11,685.00. The email costs 168 / 220 = 0.7636 minutes to read, which is 45.82 seconds; nine readers spend 0.1145 person-hours a week and 1.3745 across twelve weeks. Preparation falls to 0.5 hours a week, so 6.0000 hours in total, and the whole apparatus costs 7.3745 person-hours instead of 123.0000. The saving is 115.6255 person-hours, or $10,984.42, and the audience-time ratio between the two is 58.93 to 1.

What the numbers do not say. They do not say the meeting was worthless. A weekly call builds the working relationship that makes a hard conversation possible in week 9, and an email cannot do that. What the numbers say is that the relationship was being bought at 81 person-hours across the quarter and that a monthly call buys most of it for a quarter of the price. The right answer here was a monthly call and eleven emails, and the argument for it is a number, which is why it was accepted.

The checklist to apply.

1. Name the decision each recurring communication serves. If it serves none, it is an information transfer.
2. Price the current medium in person-hours for the actual attendee list.
3. List every slide and write the reason it survives, not the reason it exists.
4. Keep the cheapest medium that carries the decision, and schedule the expensive one for the cases that need a room.
5. Put the cut material somewhere retrievable rather than deleting it.

Worked example 3: The pie chart that cannot show the thing being claimed (India, ₹)

The message. The three states that are largest today carried 58.0% of revenue two years ago and carry 71.0% now, a gain of 13.1 points, while total revenue grew 54.5%. Concentration is rising, and the question for the board is whether that is a distribution win or a dangerous dependency.

The data. Chandra Naturals revenue by state, FY24 and FY26, in ₹ crore.

The wrong version. A single pie of the FY26 column, six slices, a legend on the right, percentages in a data-label ring, title "Revenue by State, FY26". It is wrong three ways. It shows one period, so it cannot express a claim about change, which is the entire message. Its six slices exceed what angle comparison supports: the Gujarat and Rest of India slices differ by 5.82 degrees out of 360, which no reader will resolve. And its title is a filing label that commits to nothing.

The version that seems like a fix and is not: two pies side by side, FY24 and FY26. The reader now has to hold six angles in memory and compare them to six others, which is harder than the original, and the flat ₹5.20 crore of Rest of India will read as a decline because its slice shrank.

The corrected version. A slope chart. Two vertical axes, FY24 share on the left and FY26 share on the right, six labelled lines connecting them, sorted by FY26 value, with the three rising states in one accent colour and the three falling states in grey. Direct labels at both ends carry the share to one decimal, so no legend exists. The title reads: "The three largest states went from 58.0% to 71.0% of revenue in two years."

Described precisely, the layout runs as follows. The title sits across the top in a single line. The plot occupies the middle two thirds, with FY24 and FY26 as the only two x positions and the state names and share values at both ends of every line. A single footnote gives the totals, ₹44.00 crore and ₹68.00 crore, because a share chart without its base invites the wrong reading. One annotation sits on the Rest of India line: "flat at ₹5.20 cr, so its share fell without its revenue falling".

That annotation is the slide's most valuable element and costs nine words. Without it, a reader concludes that business outside the top five states shrank. The revenue was identical in both years.

Why a slope chart and not a sorted bar. A sorted bar of FY26 share answers "who is biggest", which is a comparison message. The message here is a change between exactly two periods across a few categories, which is what a slope chart is for. If the message had been "Maharashtra is the largest state at 32.2% of revenue", the sorted bar would be correct and the slope chart would be over-built. The form follows the message, not the data.

The checklist to apply.

1. State the message as a sentence with a verb before choosing a form.
2. Classify the message type, which here is change between two periods.
3. Check the form against the grammar table and name the rejected alternative.
4. Confirm the title states the message and carries the number.
5. Check that shares are accompanied by their base.
6. Look for the reading a viewer would make that is false, and annotate it.

Worked example 4: The dual-axis chart that hid a 6.5-fold divergence (US, $)

The setting. Ridgeline Software (synthetic) is a US business-software company. Eight quarters of results, in $ millions.

The message. Operating income grew 348.1% while revenue grew 53.6%, so operating income grew 6.5 times faster than revenue. The 11.69-point gain in operating margin splits into 5.60 points from gross margin and 6.09 points from operating leverage, which sum exactly to 11.69.

The wrong version. One chart. Revenue as a line on a left axis running 0 to 70, operating income as a line on a right axis running 0 to 12, eight quarters across the bottom, title "Revenue and Operating Income". The two lines rise together and appear to move as one. That appearance is manufactured by the axis choice. At Q1 revenue sits at 60.00% of the plot height and operating income at 21.33%; by Q8 revenue is at 92.14% and operating income at 95.60%, so the operating-income line ends above the revenue line and the reader concludes the two grew in step. The divergence carrying the whole message has been scaled out of view.

Change the right axis to 0 to 20 and the story changes without a single number changing. That is the objection to dual axes, and it is not aesthetic. The author picks the scaling, the scaling picks the story, and the reader has no way to see that a choice was made.

The corrected version, option one: index both series. Set Q1 to 100 and plot the two series on a single axis, so the units are gone and only relative growth remains.

Two lines, one axis, direct labels at the right-hand end, no legend. The gap opens visibly from Q2 and reaches 294.55 index points by Q8. Title: "Operating income grew 348% against revenue's 54%: six times faster." A footnote states the base, Q1 = 100, revenue $42.0m, operating income $2.56m, because an indexed chart without its base is unreadable.

The corrected version, option two: small multiples. Three small line charts in a row on a shared 0 to 80% vertical scale: gross margin rising 68.0% to 73.6%, operating expense as a share of revenue falling 61.9% to 55.8%, and operating margin rising 6.1% to 17.8%. Each carries its own one-line title, and the row carries the claim: "Half the margin gain is pricing and product cost, half is operating leverage." Choose this version when the audience needs the decomposition; choose the indexed version when the audience needs the headline.

One honest caveat. The indexed chart flatters the smaller series by construction. Operating income started at $2.56 million, so a $8.91 million improvement reads as 348%. Say so in the footnote. A chart that is technically correct and predictably over-read is still a chart that misleads, and the fix costs one sentence.

The checklist to apply.

1. Name the message and the number that carries it.
2. If two series have different units, index them or split them, and never reach for a second axis.
3. State the base of any indexed series.
4. Check whether the form flatters one series, and annotate it if it does.
5. Order by something intrinsic, which here is time.
6. Confirm that the decomposition sums exactly, 5.60 + 6.09 = 11.69, before any of it goes on a slide.

Worked example 5: The pricing request with no decision in it (India, ₹)

The request. "Can you put together something on our pricing for Thursday?"

The wrong version. Twenty-two slides. Competitor price tables for eleven brands across four pack sizes, a price-index chart, a margin waterfall, a category growth chart, three slides on premiumisation, and a closing slide with four options and no recommendation. Build time about eleven hours. In the meeting, the first question is "so do we take the 200 ml to ₹399 in April or not?", and nothing in the twenty-two slides answers it, because the analyst never asked.

Recovering the decision. The four questions took about four minutes to write into one email. After Thursday the April price list is locked. The sales head owns it and will be in the room. What would change her mind is evidence about how much volume a ₹50 increase would cost, and doing nothing means holding ₹349 through the festive quarter.

That converts the request into a single question with a single number attached: how much volume can the ₹399 price afford to lose before it is worse than ₹349?

The corrected version. One page. One chart, one table, three sentences, and a recommendation.

The arithmetic. At ₹349 with a 62.5% gross margin, variable cost is 349 × 0.375 = ₹130.875 a unit and contribution is 349 − 130.875 = ₹218.125. At ₹399 the same variable cost gives contribution of 399 − 130.875 = ₹268.125. Breakeven volume is the ratio of the two contributions, 218.125 / 268.125 = 0.813520, so volume can fall 18.6480% before the higher price is worse. The price rise itself is 399 / 349 − 1 = 14.3266%.

The evidence about what volume will actually do comes from two past moves on the same product. From ₹299 to ₹329 was a 10.0334% price rise and volume fell 6.20%, an implied elasticity of −0.6179 measured off the starting price. From ₹329 to ₹349 was a 6.0790% rise and volume fell 3.40%, an elasticity of −0.5593 on the same basis. The midpoint convention would give slightly smaller numbers, so say which you used. The average is −0.5886, which predicts a volume fall of −0.5886 × 14.3266% = −8.4329% for the proposed move: 130,025 units against 142,000 today. Contribution rises from 142,000 × 218.125 = ₹3.0974 crore to 130,025 × 268.125 = ₹3.4863 crore, a gain of ₹0.3889 crore, or 12.56%, in a quarter.

The slide's chart is one horizontal bar with two markers on it: the breakeven volume fall at 18.65% and the predicted volume fall at 8.43%, with the 10.22 points between them shaded and labelled "headroom". Title: "Volume can fall 18.6% before ₹399 is worse than ₹349; history says it falls about 8%."

The table beneath it is four rows: price, contribution per unit, units, quarterly contribution, for the two scenarios. The three sentences state the elasticity evidence, the assumption that past moves predict this one, and the one condition that would break it, which is a competitor holding price while Chandra Naturals moves.

What makes this the right artefact. The decision is binary and the evidence is one number against another number. That is a one-pager, and the presented deck it replaced would have cost the room forty minutes to reach the same place. Total build time for the one-pager is about two and a half hours, of which the four questions were four minutes and saved roughly eight hours.

The checklist to apply.

1. Ask the four questions before building anything.
2. Restate the decision in one sentence and get it confirmed.
3. Compute the breakeven before gathering evidence, because it tells you what evidence would matter.
4. Name the assumption that carries the recommendation, here that two past moves predict a third.
5. Name the one condition that would break it.
6. Choose the medium after the analysis is scoped, not before.

Worked example 6: The board pack that had to be two artefacts (US, $)

The setting. Ridgeline Software's quarterly board meeting has a thirty-minute slot. The chief financial officer has one argument to land: operating income grew 348.1% against revenue's 53.6%, so the company should raise the sales-hiring plan for next year rather than protect margin.

The wrong version. Fourteen slides at about 180 words each, projected, read aloud. The arithmetic of that choice: 180 words takes 49.09 seconds to read silently at 220 words a minute and 83.08 seconds to say aloud at 130. The audience finishes 33.99 seconds early on every slide, which is 40.91% of the time the speaker is talking. Across fourteen slides the deck takes 19.38 minutes to say and 11.45 minutes to read, and the board spends nearly eight minutes of a thirty-minute slot ahead of the speaker. Directors read ahead, form objections privately, and arrive at question time having already decided.

The corrected version is two artefacts built from one argument.

The reading pack, circulated 48 hours ahead: nine pages at about 340 words each, 3,060 words in total, read in 13.91 minutes by any director who chooses to. It carries the full argument in prose with the exhibits inline, including the indexed chart from the previous example and the margin decomposition. It survives forwarding to a director who missed the meeting, because nothing in it depends on a speaker.

The presented deck, shown in the room: fourteen slides at about 31 words each, 434 words on screen. In a thirty-minute slot at 130 words a minute the speaker says roughly 3,900 words, so about 11% of the argument is in front of the eye and the rest is in the ear. Each slide carries an action title and one exhibit. The speaker notes carry the rest.

The third artefact nobody plans for. After the meeting, someone forwards the presented deck to a director who was travelling. Fourteen slides of 31 words each will tell her nothing. The rule that solves this: whichever artefact is likely to be forwarded gets speaker notes dense enough to reconstruct the argument, or the forwarding is done with the reading pack instead. Deciding which, in advance, is part of choosing the medium rather than an afterthought.

The cost of building both. Roughly three extra hours against the sixteen-hour budget. The alternative is one artefact that costs the board 40.91% of its attention on every slide, and a decision taken by directors who read ahead and stopped listening. Three hours is the cheaper option and it is not close.

The checklist to apply.

1. Decide whether the artefact is read or presented, and never both.
2. Size it accordingly: roughly 30 words a slide presented, 300 or more per page read.
3. Compute the read-versus-speak gap if the slide is dense, and treat anything above about 60 words a slide as a warning.
4. Decide in advance what gets forwarded, and make that artefact self-sufficient.
5. Confirm the substance is identical across both, with only depth and framing differing.

Index values as tabled, with 448.12500 − 153.57143 = 294.55357 index points of gap at Q8.

Pricing: variable cost 130.87500; contribution 218.12500 and 268.12500; breakeven ratio 0.81352, fall 18.64802%; price rise 14.32665%. Elasticities −0.61793 and −0.55930, average −0.58862; predicted change −8.43290%; units 130,025; contribution ₹3.09738 crore and ₹3.48630 crore; gain ₹0.38892 crore, 12.55645%; headroom 10.21512 points.

Reading and speaking: 180/220 × 60 = 49.09091 seconds and 180/130 × 60 = 83.07692 seconds; gap 33.98601 seconds, 40.90909% of the spoken time. Fourteen slides: 11.45455 minutes read, 19.38462 minutes spoken. Reading pack 9 × 340 = 3,060 words, 13.90909 minutes. Presented deck 14 × 31 = 434 words against 30 × 130 = 3,900 spoken, 11.13%.

Blended scores: 0.6 × 0.86 + 0.4 × 0.72 = 0.80400; 0.6 × 0.95 + 0.4 × 0.60 = 0.81000; (0.80 − 0.4 × 0.70)/0.6 = 0.86667. Hours: 8.0/16.0 = 50.00% before the tool, 5.5/16.0 = 34.375% inside it. Data dump: 30 × 60/34 = 52.94118 seconds a slide and 30 × 60/41 = 43.90244 seconds a chart; 41/3 = 13.66667 charts a claim.

Practice set

Work each one before reading the solution. A calculator is assumed. Numeric answers within 2% of the stated figure count as correct unless a problem says otherwise, and where a problem asks for a sentence, the test is whether a reader could disagree with it.

P1 (guided). Write the takeaway (India). Chandra Naturals reports revenue of ₹18.40 crore for the quarter against ₹12.90 crore a year earlier, gross margin of 62.5% against 58.0%, cash of ₹9.60 crore and a monthly burn of ₹1.30 crore. The board is deciding when to start the Series B. Write the one-sentence takeaway and show the two computations it rests on.

Solution. Revenue growth is 18.40/12.90 − 1 = 42.6357%, and runway is 9.60/1.30 = 7.3846 months. A takeaway that passes all three tests: "Revenue grew 42.6% and gross margin is up 4.5 points, but 7.4 months of runway means the raise starts in November, not February." It is a claim, because a director could argue for February. It is falsifiable, because a lower burn rate or a bridge facility would break it. And it implies an action, which is starting the process in November. A common wrong answer is "Growth is strong but cash is tight", which fails all three: nobody can disagree with it, no number could refute it, and no date follows from it.

P2 (guided). Recover the decision (US). A partner asks: "Can you look at our customer churn and come back to me next week?" Write the four questions you would ask, and state what each answer would change about what you build.

Solution. What happens after next week? If the answer is a pricing committee, you are building for a price decision; if it is a board update, you are building for information. Who else will see it? If the head of customer success is present, the analysis needs to survive someone who knows the accounts individually, which raises the evidence bar. What would change your mind? If the answer is "evidence that churn is concentrated in one segment", you now know the cut that matters and can ignore the other eleven. What happens if we do nothing? If churn costs $2.3 million a year at the current rate, that number sizes how large a recommendation has to be to be worth the disruption. The four answers together turn a week of work into two days of the right work.

P3 (guided). Price the medium (India). A team proposes a 40-slide deck at about 95 words a slide for six readers. The alternative is a two-page memo of 1,100 words. Reading runs at 220 words a minute. Compute the reader cost of each and state the choice you would defend.

Solution. The deck is 40 × 95 = 3,800 words, read in 3,800/220 = 17.2727 minutes, which is 103.6364 person-minutes across six readers. The memo is 1,100/220 = 5.0000 minutes, or 30.0000 person-minutes, saving 73.6364 person-minutes. The memo wins unless one of the three reasons for the expensive medium applies: the room, the length of the argument, or unanticipated questions. Six readers reading alone is not a room, and 3,800 words is a padded argument rather than a long one. Defend the memo, and offer a meeting if it raises questions.

P4. Three profiles, one quarter (US). Ridgeline Software's Q8 results are revenue $64.5m, operating income $11.47m, operating margin 17.79%. Write the "decides" and "fears" lines for three readers: the board, the head of sales, and a lender reviewing a revolving credit facility. Then write one takeaway each.

Solution. The board decides next year's hiring plan and fears over-hiring into a slowdown; its takeaway is that operating income grew 348.1% against revenue's 53.6%, so the margin can fund a larger sales plan without breaching the operating-margin floor. The head of sales decides quota and territory design and fears a plan she cannot hit; her takeaway is that with operating margin at 17.79% against 6.10% two years ago, the company can carry a longer ramp for new hires than the current three-month quota schedule assumes. The lender decides whether to renew the revolver and fears a covenant breach; its takeaway is that operating income has risen in all eight quarters to $11.47m, so coverage has improved every period since the facility was signed. Same eight quarters, three decisions, three sentences.

P5. Choose the form from the message (India). Chandra Naturals' channel mix, in ₹ crore: marketplaces 19.80 to 22.40, own website 8.20 to 12.90, modern trade 6.10 to 16.30, general trade 6.60 to 7.50, quick commerce 3.30 to 8.90, FY24 to FY26. The message is "marketplaces fell from 45.0% to 32.9% of revenue while quick commerce and modern trade grew about 170% each". Name the chart form, the rejected alternative, and the rule that decided it. Compute the two growth figures and the share change.

Solution. Totals are 44.00 and 68.00, which tie to the state table, so the two views are consistent. Marketplaces' share is 19.80/44.00 = 45.000% and 22.40/68.00 = 32.941%, a fall of 12.059 points. Quick commerce grew 8.90/3.30 − 1 = 169.697% and modern trade 16.30/6.10 − 1 = 167.213%. The message is a change between exactly two periods across five categories, so a slope chart of share carries it, with the two rising channels accented. The rejected alternative is a 100% stacked bar for the two years, which shows the composition but makes the individual channel movements hard to read because only the bottom segment shares a baseline. The rule: change between two periods across a few categories goes to a slope chart, and a stacked bar is for composition at a point rather than movement between two.

P6. Repair a dual axis (US). Ridgeline's revenue runs 42.0 to 64.5 and operating income 2.56 to 11.47 across eight quarters. Someone has put them on two axes. Produce the indexed series for both, state the Q8 gap in index points, and give the action title.

Solution. Indexed to Q1 = 100, revenue runs 100.00, 110.00, 120.00, 128.57, 136.19, 142.86, 148.57, 153.57 and operating income runs 100.00, 149.68, 202.31, 254.84, 308.52, 358.59, 404.38, 448.13. The Q8 gap is 448.125 − 153.571 = 294.55 index points. Title: "Operating income grew 348% against revenue's 54%: six times faster." The footnote must give the base, Q1 = 100 on revenue of $42.0m and operating income of $2.56m, because 348% on a $2.56m base is a smaller achievement than the percentage suggests, and saying so is the honest version.

P7. Cut twelve slides to four (India). A twelve-slide update contains: title, agenda, company overview, quarterly revenue, revenue by state, revenue by channel, gross margin bridge, marketing spend, acquisition cost, cash and runway, risks, thank you. The decision is when to start the Series B. Name the four slides that survive and state what each cut costs.

Solution. Survivors: quarterly revenue with growth (the credibility of the trajectory), gross margin bridge (the quality of that growth), cash and runway (the constraint that drives the timing), and a recommendation slide stating November with its two conditions. That is a 66.7% cut. Now the costs. Dropping revenue by state and by channel loses the concentration story, which belongs in an appendix because a director may ask for it. Dropping the company overview costs nothing with a board that already knows the company. Dropping marketing spend and acquisition cost loses operational detail that is the founder's decision rather than the board's, and it belongs in the ops review. Dropping risks is the only genuinely uncomfortable cut, so fold the two live risks into the recommendation slide as its conditions rather than deleting them. Agenda, title and thank-you are furniture.

P8. Compute the collision (US). An eighteen-slide deck averages 145 words a slide and will be presented. Compute the silent reading time, the spoken time, and the gap, at 220 and 130 words a minute. Then say what you would change.

Solution. Total words are 18 × 145 = 2,610. Reading takes 2,610/220 = 11.8636 minutes; speaking takes 2,610/130 = 20.0769 minutes; the gap is 8.2133 minutes, which is 40.91% of the spoken time, the same share as any dense slide because the ratio of the two rates is fixed. The change: rebuild as a presented deck at about 30 words a slide with the argument in the speaker notes, or accept that it is a reading deck and stop presenting it. Halving the word count does not fix the ratio, it only shortens both sides.

P9. Title repair (India). Rewrite these as action titles, using the figures given: (a) "Revenue by State" for a chart where the top three states moved from 58.0% to 71.0% of revenue; (b) "Marketing Update" for a quarter where acquisition cost went from ₹923 to ₹1,076; (c) "Q2 Financials" where gross profit grew 53.7% on 42.6% revenue growth. Then state the test each rewrite passes.

Solution. (a) "The three largest states went from 58.0% to 71.0% of revenue in two years." (b) "Acquisition cost rose 16.6% in one quarter, to ₹1,076." (c) "Gross profit grew 53.7% on 42.6% revenue growth, because margin added 4.5 points." Each is a sentence with a verb, each carries the number that makes it checkable, and each could be contradicted by someone holding different data. The check on (b): 1,075.66/922.61 − 1 = 16.59%, so 16.6% is the honest rounding and "sharply" would not be.

P10. Price a data dump (US). A 47-slide deck averaging 120 words a slide is circulated to eleven people. Compute the reader cost in person-hours at 220 words a minute, and state the two-line diagnosis.

Solution. Words total 47 × 120 = 5,640, read in 5,640/220 = 25.6364 minutes each, which is 282.0000 person-minutes or 4.7000 person-hours across eleven readers. The diagnosis: the deck has no takeaway, because a deck with a takeaway would have kept the slides that support it and moved the rest to an appendix; and the author is protecting themselves against the accusation of having missed something, which is a reasonable fear with an unreasonable remedy. The repair is upstream, not editorial.

P11. Triage a redline (India). Five comments arrive on a nine-slide deck.

• (a) "slide 4's margin number does not match slide 7"
• (b) "the font on slide 2 is different"
• (c) "slides 5 and 6 make the same point"
• (d) "the recommendation assumes the competitor holds price, which we have no evidence for"
• (e) "the chart on slide 8 has gridlines you do not need"

Sort them, order the work, and say why the order matters.

Solution. Substance: (a) and (d). Structure: (c). Style: (b) and (e). Work in that order. (a) is a contradiction inside the deck, which destroys trust in every other number, so it is first. (d) is an unsupported assumption carrying the recommendation, and the fix may change what the deck recommends. (c) is a merge, and it may dissolve on its own once (d) is resolved, because one of the two slides may no longer be needed. (b) and (e) take four minutes and go last. Fixing (b) and (e) first feels productive and is the reason redlines take three passes instead of one: you would have spent the four minutes on a slide that (d) later deleted.

P12. Diagnose the wrong question (US). A team spent 22 person-hours building a 26-slide deck, then presented it for 60 minutes to seven people. In the meeting it emerged that only two slides addressed the question the sponsor cared about. Compute the total person-hours committed and the share of the deck that was on target, then name the failure and the four-minute fix.

Solution. Build 22.0 person-hours plus 60/60 × 7 = 7.0 person-hours of meeting is 29.0 person-hours. On-target slides are 2/26 = 7.7%. The failure is the third arrival mode, a deck that answers a question nobody asked, and it is a briefing failure rather than an analysis failure. The fix is the four questions asked in one email before any work started: what happens after the meeting, who else is in the room, what would change your mind, and what happens if we do nothing. Four minutes against 29 person-hours is the highest-return four minutes in this branch.

Applied mini-project

One page, written before anything is built. Budget about 45 minutes. Take one analysis you have already completed, a business teardown, a case answer, a valuation, a market study, and produce the page that should have preceded it. If you have no prior analysis, use the fallback brief given after the five steps.

Step 1 names the reader and the decision, and it takes about ten minutes. One named role, not a category. "The head of category at a mid-size Indian personal-care brand" is a role; "management" is not. Write the three profile lines: what this reader already knows about your subject, what they are deciding, and what they are afraid of. If you cannot fill the decision line from what you were told, write the four recovery questions you would send and mark the line as pending. A pending decision honestly marked scores better than an invented one.

Step 2 writes the takeaway, in another ten minutes. One sentence. Then, underneath it, write the three tests and your answer to each: what claim is being made, what data would falsify it, and what action follows. Then write the strongest sentence someone could say against it. If you cannot write the counter-sentence, the takeaway is not a claim yet.

Step 3 chooses the medium and prices it, ten minutes again. Name your choice and exactly one rejected alternative. Price both in reader-minutes for your actual audience size, using 220 words a minute for reading and the meeting length for anything presented. State which of the three reasons for an expensive medium applies, or state that none does and that you chose the cheap one.

Step 4 lists the evidence and what it excludes, in the last of the ten-minute blocks. Three to six items, each one a claim you can support, each with the number that supports it. Then list what you are deliberately leaving out and where it goes. An appendix line is a decision, not a dumping ground, so name what question each excluded item would answer if asked.

Step 5 is the one-line self-check, and five minutes covers it. Write the first question you expect from your named reader. If your one page does not answer it, that is the finding, and fixing it now costs five minutes rather than a rebuild.

A note on the artefact itself. Deliver the page as a document rather than as a slide, because the point of the exercise is that the artefact choice comes last. If you export to PDF, keep it under the size your mail system will carry: most corporate systems reject attachments above roughly 20 to 25 MB, and the ceiling is set per organisation (checked September 2026; verify with your own administrator rather than assuming).

The fallback brief. Chandra Naturals is considering closing its general-trade distribution, which is ₹7.50 crore of FY26 revenue growing 13.6%, at a gross margin 11 points below the company average, to redirect the working capital into quick commerce, which is ₹8.90 crore growing 169.7%. The founder wants a view by Friday. Nothing else has been told to you. Run the five steps on that.

The rubric runs to twenty points, passing at 16 with no zero on any row.

Any row where the evidence is missing scores zero regardless of how well the page reads. The page is graded on whether it would have made the analysis land, not on its prose.

Standards and tools (free).

• W3C Web Content Accessibility Guidelines: at Level AA the contrast minimum for normal-size text is 4.5 to 1, relaxing to 3 to 1 for large text and rising to 7 to 1 at Level AAA, and the 4.5 figure is the one the accessibility rules in the mechanics branch are written against (WCAG 2.2, checked September 2026; verify, since the guideline version advances and the ratios can move with it).
• Your own presentation software's defaults: the widescreen slide in current desktop PowerPoint is 13.333 by 7.5 inches at a 16:9 ratio (Microsoft 365 desktop, checked September 2026; verify against your own installation, since the default follows the template and the release). Google Slides and Keynote use the same ratio with different measurements. The mechanics branch teaches one of these tools in depth and states the equivalents in the others.

Do this, not just read. Take the last deck you built or received and read only its titles, in order, with the slides hidden. Write down the argument they make. If they make none, you have just measured the gap this whole track exists to close, on a real artefact, in four minutes.

Flashcards

This module's flashcards and mastery quiz are wired into the app: see the node's Quiz and Reviews.

Mastery check

Two parallel forms. Closed book, calculator allowed, about 40 minutes per form. Numeric answers within ±2% score as correct unless the item states otherwise. Pass threshold: ≥ 85%. With twelve one-point items that is 11 of 12. If you score 9 or 10, redo the practice problems on the clusters you missed and sit the other form after a break.

Form A

A1 (MCQ). Which sentence is a takeaway rather than a topic or a fact? (a) An update on Q2 performance (b) Revenue grew 42.6% year on year (c) Growth is strong but cash is tight (d) Revenue grew 42.6% and margin is up 4.5 points, but 7.4 months of runway means the raise starts in November

A2 (numeric). A company holds ₹9.60 crore of cash and burns ₹1.30 crore a month. State its runway in months to one decimal place.

A3 (MCQ). A message states how six states' shares of revenue moved between FY24 and FY26. Which form carries it? (a) a pie of FY26 with six slices (b) two pies side by side (c) a slope chart of share, sorted by FY26 value (d) a sorted bar of FY26 share

A4 (numeric). FY26 revenue by state is 21.90, 15.30, 11.10, 8.20, 6.30 and 5.20 (₹ crore). What percentage of revenue do the three largest states carry?

A5 (short). Name the three lines of an audience profile and say what each one decides about the artefact.

A6 (numeric). A slide scores 0.86 on the machine and 0.72 on your committed rubric self-score. The blend is 0.6 machine plus 0.4 rubric. Give the composite to three decimal places, and say whether it passes an ordinary gate and a crown gate.

A7 (MCQ). Revenue and operating income have different magnitudes and the message is that one grew far faster. The correct treatment is: (a) plot both on two axes, scaled so the lines are comparable (b) index both to 100 at the first period and plot on one axis (c) plot revenue as bars and operating income as a line on a second axis (d) plot operating income only

A8 (numeric). A slide carries 180 words. The audience reads silently at 220 words a minute and the speaker says them aloud at 130. What share of the speaker's time on that slide has the audience already finished, in percent?

A9 (MCQ). A partner asks for "something on our pricing for Thursday". The best first move is: (a) build the competitor price tables, since they will be needed either way (b) send four questions that recover the decision, the decider and the evidence that would change her mind (c) ask how many slides she wants (d) draft a deck outline and get it approved

A10 (numeric). A product sells at ₹349 at a 62.5% gross margin. By what percentage could unit volume fall before a ₹399 price is no better than ₹349? Assume the variable cost per unit is unchanged.

A11 (short). A redline arrives with five comments: the margin figure on slide 4 contradicts slide 7; the font on slide 2 differs; slides 5 and 6 make the same point; the recommendation assumes a competitor holds price with no evidence; slide 8's chart has unnecessary gridlines. Sort them into tiers and give the order of work with one reason.

A12 (short). State what the seven-rule machine check cannot see, and say why the rubric carries 40% of the blend rather than 0%.

Form A key. A1: d. The only sentence a reasonable person could dispute, that names the data which would break it, and that implies an action with a date; (b) is a fact, (c) is a hedge that survives every outcome. A2: 9.60 / 1.30 = 7.3846, so 7.4 months. A3: c. The message is change between exactly two periods across a few categories, which is the slope chart's case; (a) shows one period and cannot express change, (b) forces angle comparison across twelve slices, (d) answers "who is biggest" instead. A4: total = 68.00; top three = 21.90 + 15.30 + 11.10 = 48.30; 48.30 / 68.00 = 71.03%. A5: What they already know sets the floor: vocabulary you may use undefined, context you may skip, caveats you must state. What they are deciding sets the target: everything that does not move that decision is decoration that costs attention. What they are afraid of sets the order: name the fear early or every question drifts back to it. A6: 0.6(0.86) + 0.4(0.72) = 0.516 + 0.288 = 0.804. It passes the 0.80 gate and fails the 0.90 crown gate. A7: b. Indexing removes the units and puts relative growth on one axis; (a) and (c) are dual axes, where the author's scaling choice manufactures the apparent relationship and the reader cannot see that a choice was made. A8: reading 180/220 × 60 = 49.09 s; speaking 180/130 × 60 = 83.08 s; gap 33.99 s; 33.99 / 83.08 = 40.9%. A9: b. The request contains no decision, no decider and no scope, and building from it produces the third failure mode; four minutes of questions is the highest-return step available. A10: variable cost = 349 × 0.375 = ₹130.875; contribution = ₹218.125 now and 399 − 130.875 = ₹268.125 at the new price; breakeven ratio = 218.125 / 268.125 = 0.81352, so volume can fall 18.65%. A11: Substance: the slide 4 and 7 contradiction, and the unsupported competitor assumption. Structure: the slide 5 and 6 merge. Style: the font and the gridlines. Work substance first, because a contradiction inside the deck destroys trust in every other number and because resolving the assumption may delete a slide; structure second, since a merge may dissolve once the substance is fixed; style last, because those four minutes are wasted if spent on a slide that later disappears. A12: It cannot see whether the title's claim is true, whether the decision targeted was the one pending, or whether the chart's message is the message that matters. It only checks that the form fits the message you declared. The rubric carries 40% because those three judgements are the ones that decide whether the deck was worth building, and a technically clean slide with a weak argument should not buy its way through: 0.95 machine with 0.60 rubric blends to 0.810, barely above 0.86 with 0.72.

Form B

B1 (MCQ). Which sentence is a takeaway? (a) Analysis of channel performance (b) Quick commerce grew 169.7% and modern trade 167.2% (c) Marketplaces fell from 45.0% to 32.9% of revenue, so the April plan should move ₹1.2 crore of spend to quick commerce (d) Channel mix has shifted meaningfully

B2 (numeric). Revenue was ₹18.40 crore against ₹12.90 crore a year earlier. Give the growth rate as a percentage to one decimal place.

B3 (MCQ). The message is "Maharashtra is the largest state at 32.2% of revenue". The correct form is: (a) a slope chart across two years (b) a sorted bar of FY26 share (c) a pie with six slices and a legend (d) a stacked column of both years

B4 (numeric). Operating income was $2.560m in Q1 and $11.472m in Q8. Indexed to Q1 = 100, give the Q8 value.

B5 (short). A weekly fifteen-slide status deck is being replaced by an email. Name four slides that should be cut and give the reason for each, then name the one slide whose content survives.

B6 (numeric). A rubric self-score of 0.70 has been committed. With a 0.6 machine plus 0.4 rubric blend, what machine score is needed to reach a composite of exactly 0.80? Give three decimal places.

B7 (MCQ). A board pack will be circulated 48 hours ahead and a version will also be shown in a 30-minute slot. The correct treatment is: (a) one deck of 14 slides at 180 words each, used for both (b) a reading pack of about 340 words a page and a separate presented deck of about 30 words a slide (c) the presented deck circulated in advance with the notes hidden (d) the reading pack projected and read aloud

B8 (numeric). A 45-minute meeting with nine attendees runs weekly for twelve weeks. How many person-hours does the audience spend in those meetings?

B9 (short). The four recovery questions return the answer that no decision is pending, and the requester simply wants to know how the quarter went. State what you do and why.

B10 (numeric). Gross margin rose from 68.0% to 73.6% of revenue and operating expense fell from 61.905% to 55.814% of revenue. By how many percentage points did operating margin rise?

B11 (short). Name the three arrival failure modes and give the repair for each in one clause.

B12 (MCQ). Which is the strongest evidence that a deck has become a data dump? (a) it runs to 34 slides (b) it contains 41 charts (c) no takeaway was written before building, so nothing selected what to keep (d) the meeting slot is 30 minutes

Form B key. B1: c. The only one that makes a disputable claim and names an action; (b) is two facts, (d) is a hedge, (a) is a topic. B2: 18.40 / 12.90 − 1 = 0.426357, so 42.6%. B3: b. The message is a comparison across categories at one date, which is the sorted bar's case; the slope chart in (a) is for change between two periods, and (c) fails on angle comparison above three slices. B4: 11.472 / 2.560 × 100 = 448.13. State the base alongside it, because 348% growth on a $2.56m starting point is a smaller achievement than the percentage suggests. B5: Any four of these. The agenda goes because an email does not need one, the objectives because they are unchanged since week 1 and already signed, the team and roles because they are unchanged and belong in the charter, the workstream map because it pictures the plan rather than progress. So do the milestone chart, where schedule status is one number; this week's and next week's activity lists, which nobody decides on; the baseline analysis, complete in week 3 and restated ever since; and the process maps, which are deliverables already circulated. The survivor is the decisions-needed slide, which is the only one carrying a decision. B6: (0.80 − 0.4 × 0.70) / 0.6 = (0.80 − 0.28)/0.6 = 0.867. B7: b. The two artefacts have opposite jobs, and the hybrid costs the room 40.9% of every slide; whichever version gets forwarded afterwards needs notes dense enough to stand alone. B8: 45/60 × 9 = 6.75 person-hours a week; 6.75 × 12 = 81.0 person-hours. B9: Say so before building, and send the information in writing. A communication with no decision attached is an information transfer, and an information transfer belongs in the cheapest medium that carries it accurately, which is an email or a one-pager rather than a meeting. Naming the absence is the professional act; the failure is spending a day building as though a decision existed. B10: gross margin adds 73.6 − 68.0 = 5.600 points; the expense ratio adds 61.905 − 55.814 = 6.091 points; the total is 11.691 points, and the two components must sum to the total exactly, which is the check. B11: The data dump, repaired upstream by writing the takeaway and moving the unchosen material to an appendix rather than by editing slides. The beautiful empty deck, repaired by reading the titles alone and rebuilding the argument the title stack fails to make. The deck that answers a question nobody asked, repaired before any work by the four recovery questions. B12: c. The slide and chart counts are symptoms and can be innocent on a long analytical document; the cause is that no takeaway existed to select against, which is why cutting slides does not fix it.

Teach it back & journal

Feynman prompt. Explain to a competent colleague who has never thought about this why two decks with identical data can have opposite value, without using the words design, professional or polish. Use the arithmetic. A projected slide of 180 words takes 49 seconds to read and 83 to say, so the audience spends 41% of every slide waiting. A 45-minute weekly meeting for nine people costs 81 person-hours a quarter, against 1.4 for the email that carries the same decision. And 22 person-hours of building plus a 60-minute meeting for seven is 29 person-hours spent on a deck where 7.7% of the slides touched the real question. Then make the harder point: none of those numbers is about slides. Each one is about a decision that was or was not identified before the work started. If your colleague can tell you, unprompted, what the four recovery questions are for, you have taught the idea rather than the arithmetic.

Journal prompt. Find the last deck you built, or the last one somebody sent you, and run three checks on it. First, hide the slides and read only the titles in order: does an argument follow, or is it a table of contents? Second, write down the decision that deck was serving, in the words the decider would use, and note honestly whether you can. Third, price the medium: how many people, how many minutes, and what would the same content have cost as a memo? Write down the three answers. Then write a paragraph on which of the three arrival failure modes is yours, with the evidence from your own artefact rather than from a description. Data dumpers are usually analysts with real depth who are afraid of being caught not knowing something; empty-deck builders usually have design instincts and no ownership of the argument; wrong-question builders are usually eager and under-briefed. Being wrong about which one you are is common and costs a branch of frustration, so use the artefact rather than your self-image. Finish with one habit you will install this week, and make it small enough to survive a bad Tuesday: a text file open before the software, one sentence written in it, and a rule that the software stays shut until the sentence could be argued with.
