The best PMs make PRDs invisible

I have written hundreds of PRDs. I have read hundreds more, written by teams I was coaching. In all that time I have never met a person who was glad the document existed.

That sounds like a complaint about writing. It is not. The best product managers I work with still do every bit of the thinking a PRD demands. They simply stopped making everybody else read it.

Here is the argument in one line: the PRD was never the point. Alignment was. And the document is no longer the best way to get it.

Why we wrote them in the first place

Product managers have been writing PRDs since roughly the dawn of the role, and not because anyone enjoyed the exercise. They wrote them because a product team of two or more people, which is every product team, either agrees on where it is going or watches the product drift somewhere nobody chose.

The PRD did a real job. It was the single place where the problem, the scope, the rationale, the edge cases, and the definition of done all lived. When someone asked "wait, are we also doing the bulk upload," there was an answer, and it was written down before the argument started.

So the instinct behind the document is right. Ambiguity in a product team is expensive, and it compounds. The instinct was never the problem.

The document was always the weak link

PRDs are extensive. That is the polite word for it. They are hard to write and they are harder to read, and the second half of that sentence is the one that actually costs you.

Because the failure mode is rarely that the spec was wrong. The failure mode is that it went unread. The engineer skims the requirements section. The designer skims the user stories. The stakeholder reads the first paragraph and the deadline. Nobody holds the whole thing in their head at once, including, three weeks later, the person who wrote it.

Then you find the misalignment in sprint review, which is the most expensive room in the building to find it in.

The thinking does not go away

This is the part people get wrong when they hear "make PRDs invisible," so let me be blunt about it. Invisible does not mean skipped.

What problem are we solving. For whom. What evidence says it is real. What outcome should move. What we are deliberately not doing. That work still has to happen, and no prototype does it for you. It is the same reasoning chain that runs from an outcome down to a validated bet, which is exactly what you are doing when you build on evidence rather than a hunch.

Skip that and generate screens instead, and you have not removed the document. You have made a prettier guess.

Turn the words into screens

Here is what changed. You can now take that same thinking, feed it into an AI product design tool, and get a working prototype of where you want the product to be at the end of the next sprint. What used to be a week of production work is now an afternoon.

A prototype beats a document as an alignment artifact for three specific reasons.

People finish it. A twelve-page spec has a completion rate. A prototype has a click-through. Everyone in the room actually consumes the whole thing, which is not something you can say about page nine.

It surfaces disagreement immediately. Two people can read the same paragraph and picture two different screens, and both will nod. They cannot look at the same screen and picture two different screens. The argument you were going to have in sprint review happens in the kickoff instead, which is where you want it.

You can put it in front of a customer. This is the one that matters most. A prototype is testable on Thursday. A PRD is not. The document could only ever align the people who built the thing, never the people who were supposed to want it.

Three ways this goes wrong

I have watched all three happen, so they are worth naming.

The prototype becomes the spec. Happy-path screens are seductive, and they are silent about error states, permissions, empty states, and what happens when the payment fails. Keep the written version. Just stop making it the thing you present. It is the backing store, not the interface.

The prototype gets thrown over a wall. If the designer and the engineer see the screens for the first time in the kickoff, you have not removed the handoff, you have only made it prettier and faster. The point of working as a product trio is that all three of you were in the decision, not that one of you narrates it better.

The PM becomes a prototype factory. Cheap artifacts create demand for more artifacts. If your week is now spent generating screens on request instead of deciding what is worth building, you have swapped one form of order-taking for another, which is the same trap as administering a backlog and calling it product management.

How to make yours invisible next sprint

Take the next PRD you were going to write. Write it. Do not publish it.

Then pull out the part that fits in a paragraph: the problem, who has it, the evidence, the outcome you expect to move, and what is explicitly out of scope. Turn the happy path into five to eight screens. Run the kickoff off the prototype, with the document open in another tab for the moment someone asks about the failed payment.

Then count how many questions arrive in the first twenty minutes. Those are the ones that used to arrive in sprint review.

If your team keeps discovering the disagreement late, that is usually a decision-making problem rather than a writing problem, and it is the kind of thing our product advisory work is built to unpick.

The PRD is not dead. It moved backstage, which is where it always belonged.
