How to Do First Principles Thinking Using AI (With Prompts You Can Actually Use)

Use AI to question a workflow before you ask it to speed the workflow up. Here are six prompts, run in order on one worked example, and what to check at each step.

TLDR: Asking AI to speed up a process nobody has questioned just produces the same process faster. Six prompts take a workflow from its purpose to a pressure-tested redesign, with the AI doing the challenging and a named person owning every answer.

The Short Version

Before you automate a recurring task, use six prompts in order: name the job, list and sort the assumptions, argue against the task, redesign from a blank page, bring the constraints back, and pressure-test the result. A filled-in context sheet, a sorted assumption list and a four-question pre-automation check make each step usable, and the model drafts while a named person decides.

Why a faster process isn't always a better one

Most teams asked to use AI on a recurring task start by speeding up the steps they already have, and the steps themselves rarely get questioned. The weekly update gets drafted in half the time. The approval email gets a summary. The work moves faster, and the same people receive the same document they were already skimming.

An operations analyst who owns a weekly sales deck is a typical case. Thursday afternoon goes on matching account names across three exports, pasting figures into a slide template and writing a page of commentary. Told to use AI, the analyst tries a prompt that drafts the commentary. It works, the deck is finished earlier, and it still goes to the same readers, most of whom stop after page one.

The fix is an order of operations. Before you ask AI to improve a workflow, use it to question the workflow: what it’s for, what it assumes, whether it should exist, and what you’d build today. This guide gives you six prompts to do that, run in order on one worked example, with a note on what a good and a weak answer look like.

None of this is a new idea. Michael Hammer’s 1990 Harvard Business Review article carried the headline “Don’t Automate, Obliterate,"[1] and Jason Averbook has made a version of the same argument about AI: organizations add AI to broken or outdated processes and mistake faster execution for progress.[2]

One thread runs through all six prompts. The AI does the challenging, and a named person owns every answer.

What first principles thinking asks of you at work

First principles thinking sounds grander than the work needs. In practice it’s three questions, asked in order. What is this actually for? What’s true here that would stay true whatever we chose? If we were starting today, with today’s tools, what would we build?

Jensen Huang, NVIDIA’s chief executive, describes the habit in a Stanford Graduate School of Business interview: he goes back to first principles “all the time” and asks, given how things have changed, how he’d redo something.[3] He puts the test as a question about the underlying facts. Did physics change? Did gravity change? If not, the direction may still be sound. If the tools changed, the way you get there may not be.

That second half is the useful one for AI. Many workflows were shaped when drafting, matching and summarizing were slow for a person. A step that exists because “someone has to write it up” rests on an assumption AI changes. A step that exists because finance needs a signed-off number doesn’t.

AI helps with the questioning in four ways:

  • It restates the work’s purpose without today’s baggage.
  • It surfaces assumptions you’ve stopped noticing.
  • It argues the case nobody wants to make in a meeting.
  • It proposes alternatives without caring whose process it was.

It’s weak in two places. It doesn’t know your facts: the contract term, the regulation, the thing your finance partner won’t move on. And it tends to agree with whoever is talking, which is why prompt 3 below is built the way it is.

The six-prompt pass

1Name the jobWhat the work is for, with no method in the sentence
2List assumptionsSort each one: fact, policy, habit or tool limit
3Argue against itThe case for stopping or shrinking the work
4Redesign blankThree designs built only from the purpose and the facts
5Bring constraints backSee what each design breaks
6Pressure-testHow it fails, and who would catch it

The sequence this guide follows. Each prompt uses the previous answer, so run them in one conversation.

The weekly deck we'll run every prompt on

Every prompt below starts from the same one-page description of a piece of work. The prompts are only as good as what you paste in, and without context a model fills the gaps with plausible generalities, which gives you an answer that could be about anyone’s deck.

The context sheet, filled in for the weekly sales deck

FieldWhat goes in it
The workWeekly sales deck
Who does it, and whenOne operations analyst, Thursday afternoon, most of the afternoon
InputsA CRM pipeline export, a billing system export, and a forecast spreadsheet kept by the regional leads
Steps todayPull the three exports. Match account names by hand, because the systems spell them differently. Paste figures into a slide template. Write a page of commentary from memory of what was said in calls. Save as PDF and email it.
What comes outA long deck. The first two slides carry the numbers.
Who gets itRegional leads, the sales director and a finance partner
What we think they do with itLeads skim page one. Finance checks one table. The director reads it before the Monday forecast call.
Known painAccount names don’t match. The commentary is thin. The figures are a few days old by Monday.
Constraints we know are realFinance needs a signed-off number at month end. The CRM is the record for pipeline.
What we don’t knowWhether anyone reads past page one. Whether finance needs it weekly.

Paste this above each prompt, with your own work in place of ours.

The last two rows are the ones people tend to leave blank. Fill them in first: prompt 3 leans on what you don’t know and prompt 5 on what you do.

Leave out customer names, employee details and anything your organization’s AI policy keeps out of these tools. If you’re unsure what that covers, ask whoever owns AI governance first. The prompts were tried on this sheet before they went in, but your output will differ with your context and your tool. Read it as a draft from a sharp colleague who hasn’t met your company.

Prompts 1 and 2: name the job, then list what you've assumed

The first prompt does one job: it makes you say what the work is for without describing a single step.

Prompt 1: name the job

Here is a description of a recurring piece of work:

[PASTE THE CONTEXT SHEET]

Write what this work is for in one sentence, without mentioning any of the current steps, tools or file formats. Then tell me who uses the result, what decision or action it supports, and what would happen if it stopped for a month. Where you’re guessing, say so, and list what I’d need to find out.

A good answer names a person and a decision, such as helping the sales director agree the forecast before Monday. A weak one says something like “provides visibility into sales performance”, which has no decision in it. Reply: “Name the decision.”

The Job-First Rule

Write down what the work is for before you describe how it’s done.

Once the purpose is fixed, the second prompt goes after everything you’ve been taking for granted. It asks for sorting as well as listing, because what comes next depends on which assumptions are open.

Prompt 2: list and sort the assumptions

Using the purpose we just agreed, list every assumption built into how this work is done today: about timing, format, who does what, who receives it, and which tools are involved. Aim for at least ten. Label each one FACT (true whatever we choose, such as a law or a contract), POLICY (a choice someone made and could change), HABIT (nobody decided it, it grew) or TOOL LIMIT (it exists because of how a system works today). Add one line on how I could check it. Don’t redesign yet.

If the list is short or generic, add your known pain points to the context sheet and run it again.

What a good answer to prompt 2 looks like (six of the rows)

AssumptionTypeHow to check it
The deck goes out weeklyHabitAsk the director which decisions need a weekly view and which a monthly one
Account names have to be matched by handTool limitAsk the CRM and billing owners whether a shared account ID exists
The analyst writes the commentaryPolicyAsk who decided that, and whether leads add their own
Everyone gets the same documentHabitAsk each group what they use
Finance needs a signed-off figure at month endFactConfirm with the finance partner. This one stays.
The CRM is the record for pipelinePolicyCheck with the sales director. Changing it is a bigger decision than this deck.

The type label is the model’s first guess. The person who owns the rule decides whether something is really a fact.

Several labels will be wrong, and the cost is uneven. A habit that’s really a contractual commitment gets cut by mistake, and a fact that’s really a habit rarely gets challenged. Check the fact and policy rows with whoever owns them before you go on.

The Sort-Before-You-Cut Rule

Facts stay, policies need their owner, and habits and tool limits are open to change.

Prompt 3: ask whether it should exist at all

Asking whether a process should exist is the hardest question to put to your own team, which makes it a good job for a tool with no stake in the answer. The catch is that the tool has a lean.

A 2023 paper led by Mrinank Sharma found that five AI assistants showed sycophancy, a tendency to match what the user seems to believe, and that in existing human preference data, responses agreeing with a user’s views were more likely to be preferred.[4] In practice, if you ask “is this deck still worth keeping?” in a tone that signals you like it, the answer tilts your way.

So prompt 3 doesn’t ask for a verdict. It asks for the two strongest cases, one after the other, and tells the model not to be polite.

Prompt 3: argue against it

Act as a skeptical colleague with no stake in this process. First, make the strongest case that this work should be stopped, merged into something else, or cut to a fraction of what it is now. Use only what’s in the context sheet and the assumptions list, and point to the assumptions you’re leaning on. Then make the strongest case for keeping it as it is. Finally, give me the one question I should ask the people who receive it, and say what answers would settle the matter. Don’t flatter the current process, and don’t pretend to know facts you haven’t been given.

A good answer points at specifics from your sheet, such as pages two onward being a cost nobody has defended, and ends with a question you can ask, such as “If this stopped for four weeks, who would notice first?” A weak answer lists pros and cons in balance. Ask for the strongest case only, and add a fact it can use.

Treat the output as a hypothesis. The model has only your sheet, so the real test is the question it hands you. Take it to two or three of the people who receive the deck, as a question and not a pitch. What they say outweighs the model.

If you’re the analyst, have that conversation with your manager first, because retiring a deck is their decision. If you’re the manager, you can ask the recipients without it sounding like a threat.

Prompts 4 and 5: redesign from a blank page, then bring the constraints back

With a purpose, sorted assumptions and a challenge on record, you can build from a blank page. The prompt gets only the purpose and the facts. Everything else stays out until the next step.

Prompt 4: redesign from a blank page

Forget how this work is done today. Using only the purpose and the items we labelled FACT, design three different ways of achieving the purpose from scratch. Make them genuinely different from each other: one that uses no new software, one that removes a recurring human step, and one that doesn’t produce a document at all. For each, describe in plain steps what happens each week, who does what, and what would be lost compared with today. Don’t keep a step just because it exists now.

A good answer gives three options that differ in kind. A weak one gives three versions of the same deck in different formats. Reply: “Option B is today’s process with a new name. Start again without a document.”

Prompt 5: bring the constraints back

Now bring the constraints back. Here are the POLICY items and TOOL LIMITS from our list, plus anything I’ve added:

[PASTE THEM]

For each of the three designs, tell me which constraints it breaks, which it works around, and what I’d need to find out before trying it. Rank the designs by how little they depend on changes I don’t control. Don’t pick one for me. Tell me what would make you choose each.

Check that it names a constraint from your list, not a generic risk. If not, ask it to cite the row.

What good answers to prompts 4 and 5 look like, side by side

OptionWhat happens each weekWhat’s lostWhat it needs
A: One live viewPipeline and billing sit in one shared view that updates itself. The analyst checks the account match once and fixes exceptions.The narrative. Nobody explains why a number moved.Billing data reachable from the CRM view. Check with whoever owns both systems.
B: A change noteA short Thursday note lists only what changed since last week, flags a handful of deals, and carries one table for finance.The full picture each week, and context for someone new.A stable account ID to see what changed. A source for the month-end figure.
C: A standing slotThe director and leads walk one table in a short slot on the Monday call. The analyst brings the questions.A written record, and anyone who can’t attend.The director agreeing to give up the document.

The kind of options a good response produces for this sheet. Yours will differ.

A finance controller reads the one-page change note and asks where the signed-off month-end number comes from, because the old deck had a table for it. Nobody had put that on the constraint list. It was a missing fact, and this is the cheapest place to find it, before anything is built or automated.

Pick the option that needs the fewest changes you don’t control, and run it alongside the old deck for a few weeks. The model can rank the options, but it can’t know which colleague will say no.

Prompt 6: pressure-test it before anyone automates it

Only now does automation become the question. A redesigned process can still be a bad one, and the quickest way to find out is to make the model run it for a year.

Prompt 6: pressure-test the redesign

Here is the design we’re leaning towards and the purpose it serves:

[PASTE THE DESIGN AND THE PURPOSE]

Play an operations lead who has to run this for a year. Tell me how it fails in month three, what it quietly depends on that nobody has written down, and which part is most likely to produce a wrong output that looks right. Then answer this: if we automate it as described, are we speeding up a good process or a bad one? Name who would catch the first wrong output and how long it would take them. If you can’t tell from what I’ve given you, say what’s missing.

A good answer names failure points tied to your design, such as a renamed CRM field silently dropping a deal from the change note, or a note that hides the one quiet deal that matters because it didn’t change. A weak answer says “data quality” and “change management”. Paste the actual steps and ask for the single likeliest failure.

This is a close cousin of the pre-mortem prompt in our piece on running a pre-mortem before a big decision. Use that one for a decision and this one for a process. For the order of work in a teardown, see fixing broken workflows before you collect more tools. Before anyone automates anything, score the design on four questions.

The pre-automation check: score each question 2, 1 or 0

QuestionScore 2 ifScore 0 if
1. PurposeYou can state what the work is for in one sentence that names a decisionYou can only describe the steps
2. Habits testedEvery habit assumption has been put to the people who receive the outputThe habits are still assumed
3. ConstraintsThe chosen design survives the full fact and policy listA constraint is unchecked or unknown
4. Catching errorsA named person can tell within minutes that an output is wrongNobody would notice until a reader complains

Score the design, not the idea. Use the bands below.

  • 7 to 8: Automate a first version, with a named reviewer.
  • 4 to 6: Fix the lowest-scoring question first, then score again.
  • 0 to 3: You’re speeding up a process you haven’t examined. Go back to prompt 3.

The check, scored for the weekly sales deck after one pass

QuestionScoreWhy
1. Purpose2It names the director’s Monday forecast decision
2. Habits tested1Regional leads were asked. Finance wasn’t.
3. Constraints1Where the month-end figure comes from is still unconfirmed
4. Catching errors1The analyst would notice, but nobody checks on a schedule

Total 5, so fix before automating: confirm the month-end source with finance, then name a reviewer and a weekly check.

The Redesign-First Rule

Automate a process only after you’d choose to build it that way today.

What the AI does, what you still own, and what to do this week

Here is where the model’s job ends and yours begins, step by step, for the weekly sales deck.

What AI does, what you still own, and how it’s checked

StepWhat AI doesWhat the human still ownsHow it gets checked
Prompts 1 and 2Drafts the purpose and sorts the assumptions into four typesDecides what the work is for, and confirms facts and policies with their ownersEach fact and policy row is confirmed by its owner before prompt 3
Prompt 3Argues both cases from the sheet and drafts the question for recipientsAsks the recipients, then decides whether to stop, shrink or keep the workTwo or three recipients answer. The manager who owns the deck agrees the result.
Prompts 4 and 5Proposes three different designs and shows what each one strainsChooses one to trial and finds out the unknownsThe owner of each constraint, such as finance or IT, reads the chosen design
Prompt 6Plays the skeptical operator and names likely failure pointsDecides whether to automate, and who reviews the outputsA named person spot-checks one output a week at random

The model drafts and challenges. A named person decides.

Who does what depends on the role. The analyst who owns the deck runs the prompts. The sales director, as the person who uses it, answers the question from prompt 3. The finance partner confirms the facts and policies that touch finance, and whoever owns the CRM and billing systems confirms the tool limits. For a recruiter reworking interview scheduling, the prompts stay the same and the people holding the facts change.

When you run the redesign, judge it on three things, in this order:

  • Use: are the recipients opening the new version?
  • Persistence: a month later, are they still using it without a reminder?
  • Impact: did the Monday call change, or did the analyst’s Thursday go to analysis instead of assembly?

Counting how many people ran the prompts measures access, not whether the work changed.

A team can run this pass on its own, and many do. Structured training with an experienced facilitator shortens the learning curve and builds the habit of questioning a process across a team instead of in one enthusiastic person (our corporate workshops are built around that). In the terms we use at Future Factors, training builds the capability to question a process. The context sheet and the ownership table are workflow design, which gives that capability somewhere to be used. Reinforcement is a manager asking in week four what the pass turned up. Adoption is what you see when that holds, as covered in our guides on driving AI adoption on non-marketing teams and adding AI to your workflows. For more prompts that argue back, see the best prompts from the internet, tested and explained.

This week:

  1. Pick one recurring piece of work you own and fill in the context sheet, including the last two rows.
  2. Run prompts 1 to 3 in one conversation.
  3. Ask the one question the model gives you to two people who receive the work.
  4. Only then decide whether prompts 4 to 6 are worth running.

Frequently Asked Questions

Which AI tool works best for first principles thinking?

Any general chat assistant can run these prompts, including ChatGPT, Claude and Microsoft Copilot Chat. The context sheet matters more than the tool, and so does whether your organization allows the tool for work content.

What do I do when the answers sound smart but generic?

Generic answers usually mean the model is missing a fact. Add the known pain and constraints to the context sheet, then ask: “Which sentence in your last answer would be false for my situation?”

Does first principles thinking mean throwing everything out?

No. Facts stay, and policies stay until their owner agrees to change them. In the sales deck example, the month-end figure survived every redesign. Often what changes is the format, the frequency or who receives it, not the purpose.

Is it safe to describe my workflow to an AI tool?

Describe the work in plain words and leave out names, figures and anything your AI policy restricts. If you don’t know the policy, ask whoever owns AI governance.

Who should run this, me or the whole team?

Start with whoever owns the recurring work, because they hold most of the context. Bring in the recipients for prompt 3 and the people who own the facts for prompts 2 and 5.
