How to write a product strategy document

A product strategy document sets out the few choices that decide what your product will and won't do. That means which customers you serve, how you'll beat whatever they use today, and what you'll leave out. A good one names the option each choice beat, dates the evidence behind it, and says what would prove it wrong. It runs a few pages of prose and comes before the roadmap, which lists what gets built and when.

One test matters more than the rest: a sentence is a choice only if a sensible person could argue for the opposite. Apply it to every line before you polish any of them.

Gather the drafts and the evidence

Start with everything that already claims to be strategy: the current draft, the board deck, last year's strategy and the company plan this one sits under. Keep the versions that disagree. Where two drafts contradict each other, you've usually found a decision nobody has made yet.

Then collect the evidence behind the numbers: market research, win and loss notes, customer interviews and product analytics. Next to every claim, write the date of its source, not the date of the slide that repeats it. A 2023 report quoted in a 2026 deck is a 2023 claim.

This template marks any source over 18 months old as stale. Old market sizing gets a second flag, since that number usually carries the most weight and gets rechecked least. If a claim cites a trade article, find the original research or drop it. When you need a fresh market estimate, build it from sourced figures instead of reusing an old headline.

Test every statement for a real choice

Copy each strategic statement into one list, word for word, since paraphrasing quietly repairs weak lines. Roger Martin, co-author of Playing to Win, asks whether the opposite of your choice is stupid on its face1. If it is, you haven't made a strategic choice. Nobody argues for a worse user experience, so "We will deliver an exceptional user experience" fails.

Martin's proof that an opposite isn't stupid is that rivals choose it and still succeed. A competitive positioning map shows who made which bet. Lines that fail are what he calls operating imperatives, things you must do just to keep up. Keep them on a separate list, and limit the real choices to three to five, the range he suggests.

Marty Cagan, founder of Silicon Valley Product Group, says he keeps finding companies with "a list of literally 50 major objectives or initiatives"2 on a wall or spreadsheet. Their product teams, he writes, are committed to more than 100% of their time.

Each line that passes faces two more questions. Did someone you work with actually argue for the opposite? Write down their name and their case, because an alternative nobody championed is usually a straw man. And what would show the choice is wrong? Pick a number someone already watches, not "if the market shifts."

ExampleThree lines from one draft, testedAn illustrative example written for this guide, from the template's made-up construction software company.

"We will win with the general contractor as our primary buyer." The VP of Sales argued for selling to subcontractors first. The choice is wrong if over a third of new revenue comes from firms that aren't general contractors, two quarters running. Verdict: a choice.

"We will invest in AI to accelerate customer workflows." Every rival would sign it, and it doesn't say what it displaces. Verdict: an initiative until it does.

"We will focus on mid-market firms of 50 to 500 employees." Nobody argued for another segment this year, and the median customer already has 140. Verdict: a description of today's customers.

  • A named opponent. A colleague made the opposite case, and a number someone already tracks would reverse the decision.
  • Specific isn't the same as chosen. The segment line has numbers in it, but nobody argued for anything else. It describes the present.

Settle contradictions, then list what you won't do

Next, read the surviving choices against each other and against the roadmap. In his 1996 HBR article What Is Strategy?3, Michael Porter describes how Continental Airlines launched Continental Lite to match Southwest's cheap point-to-point flights while staying a full-service airline. He calls this straddling. Continental lost hundreds of millions of dollars, and its CEO lost his job.

Product drafts straddle in familiar ways. A self-serve growth plan sits beside a buyer who runs a 90-day committee review, or "mobile-first" sits beside a product whose main users work at desks. Don't soften both lines until they fit. Decide which one the company is doing this year, judging by where money and people go, and move the other to the not-doing list.

In Porter's words, "The essence of strategy is choosing what not to do." Build the not-doing list from the alternatives that lost, and record who argued for each, its strongest case and the condition that would bring it back. Without that condition, a declined idea tends to get argued again at every planning meeting.

Write down what would prove you wrong

Every choice rests on beliefs about customers, competitors and costs that aren't settled yet. Martin calls "What would have to be true?"4 the most valuable question in strategy. In his experience, teams that disagree about the facts can almost always agree on the logic of a choice. Then they can agree in advance on the evidence that would settle it.

Write each assumption as a claim about the world, then give it a threshold and a date, so it can come back false. If the evidence is two years away, call it a review item, not a live test.

Turning a belief into a test

AssumptionVague checkWhat would prove it wrong
Customers consolidate onto one platformWatch account expansion3 or more of our top 40 accounts add an overlapping tool within a year

Owning financial data keeps customers longerMonitor retentionFinancials-only accounts retain under 5 points better than field-only ones at 24 months, by end of Q4

Illustrative rows, based on the template's sample company.

Recheck the list as evidence arrives. When something that had to be true stops holding, Martin says to revisit the strategy "right now," not at the next planning cycle. Run the cheapest tests first: a handful of discovery calls can settle the assumption behind a two-country expansion before any engineering starts.

Write the product strategy document as prose

The final document should be prose, not slides. Jeff Bezos wrote in Amazon's 2017 letter to shareholders that the company doesn't use slide presentations. It writes "narratively structured six-page memos"5, and a great one "might take a week or more." Prose forces the reasoning to connect: this buyer, therefore this product, therefore this way of selling. The template's two-to-four-page narrative follows this order:

  1. Where you stand

    The situation in current numbers, with any stale figure dated or dropped.

  2. The choices

    One paragraph each, naming the alternative it beat and why it lost.

  3. The bets

    The two or three assumptions that would change everything, with their tests and dates.

  4. What you won't do

    A short not-doing list, with what would bring each item back.

  5. What's still open

    The questions this strategy doesn't settle yet, stated plainly.

Before you share it

  • Every choice names the alternative it beat and who argued for it
  • Each choice has a switch trigger someone will notice
  • No two choices imply different buyers, products or ways of selling
  • Every factual claim shows its source's date
  • Each assumption has a threshold and a deadline
  • The not-doing list names real options, each with a way back in

Once the strategy holds, your product roadmap should follow from it, and RICE scoring can rank the work that serves its choices. To start from your own drafts, open this template in River, which tests each statement and dates each claim for you.

How to use this template

Use the files as they are, or open them in River. River asks for your draft strategy and the research behind it, then tests each statement for a real alternative and the person who argued for it. It tells you how many statements are actual choices, then dates every factual claim and looks for the current edition of any source over 18 months old.

Starting from a blank page? River asks which decision your team is arguing about most and makes it the first row of the Choice Register. A live disagreement already has someone on each side.

  1. Download it or open it in River

    Download the four Word documents and three CSV sheets with no signup, or open them in River to start with your own drafts.

  2. Test every statement

    Put each line of your draft in the Choice Register with its alternative, its advocate and its switch trigger.

  3. Date evidence, test assumptions

    Log each claim's source date in the Evidence Register, and give every assumption a test and a deadline.

  4. Write the documents and share them

    Draft the narrative, the choices and the not-doing list yourself, or ask River to write them from your registers.

Three choices, eight descriptions. Report the ratio before critiquing any single line, because it is arithmetic rather than taste. The descriptions are not badly written: they are usually the best-written lines in the draft, which is what a sentence with nothing contested in it reads like. They get reclassified rather than deleted, three to operating principles, three to initiatives, two gone. The two contradictions are decisions waiting to happen: a 90-day committee evaluation is not a self-serve motion, and the accountant reading budget-to-actual on two monitors is not a mobile-first user.

RiverEvidence Register

Evidence Register

Every factual claim in the draft, with the date of its source rather than the date of the slide. Anything over eighteen months old is flagged, and market sizing is flagged twice.

Five stale, five current, and every stale claim is external while every current one is internal. That is the pattern: the numbers about the outside world are the ones nobody owns. The 41-month market sizing is the entire quantitative basis for entering two countries, and the strongest current number in the register argues against the choice the company actually made. Both facts belong in the narrative rather than out of it.

Assumption and Risk Log

The cheapest test in the log sits underneath the most expensive choice: five discovery calls settle a two-country expansion, and they should happen before the engineering does. The most consequential test is the retention comparison, because the choice the whole product rests on is contradicted by one of the freshest numbers in the evidence register and nobody has yet measured the thing that would settle it. The last row is honest about being a review item rather than a check, which is better than leaving it in the log looking checkable.

Common questions

What should a product strategy document include?

It should include where the product stands today, three to five choices about who you serve and how you'll win, and the option each choice beat. Add the assumptions each choice depends on, each with a test and a date, and a list of what you've decided not to do. Supporting sheets can hold the full evidence and assumption logs.

What is the difference between a product strategy and a roadmap?

A product strategy explains why you're building one set of things instead of another: who the product is for, how it wins and what it won't do. A roadmap says what gets built and when. The roadmap should follow from the strategy. If it funds work the strategy never mentions, the roadmap has quietly become the real strategy.

How long should a product strategy document be?

Short enough to read in one sitting. The template's narrative aims for two to four pages of prose, covering each choice, the alternative it beat and the key bets. The longer registers of claims and assumptions live in separate sheets, so the main document stays readable for people who weren't in the meetings.

How often should you update a product strategy?

Update it when the evidence says so, not only when the calendar does. Check switch triggers and assumption deadlines every quarter, and revisit a choice as soon as its trigger fires. A full review once a year, ahead of annual planning, keeps the document from drifting away from what the company actually does.

Is this product strategy template free?

Yes. Download the four Word documents and three CSV sheets with no signup. They come filled in for a made-up construction software company, so you can see how each file works before replacing it with your own strategy. Edit with AI opens the same template in River.

What does Edit with AI do?

It opens the template in a free River workspace. River asks for your drafts and the research behind them, then tests each statement for an alternative someone argued for and a switch trigger, and dates each claim. From the finished registers it can write the narrative and the not-doing list, and later answer "why aren't we doing X?" questions.
