You spent most of a day on the PRD. Problem statement, goals, non-goals, user stories, edge cases, the little diagram. You shared it. Two people skimmed the summary. Engineering asked, in the standup, a question the document answered on line forty. Nobody read past the fold, and the feature got built off a Slack thread and a hallway conversation anyway.
The standard reaction is guilt and a resolution to write better ones. Shorter. Punchier. A better template. That is treating a structural failure as a personal one. People are not failing to read your PRD because it is too long or you buried the point. They are not reading it because of what a PRD is: a document that was finished the moment you wrote it, sitting somewhere the actual work does not live.
A PRD is dead on arrival by design
A PRD is a snapshot. It describes what the product should be at the instant you stopped typing. That is its whole nature, and it is the root of the problem, because a product is not a snapshot. It is a thing that changes every day as decisions get made, code gets written, and reality pushes back.
So the gap opens immediately. The day after you publish, an edge case turns out to be wrong, a constraint appears, a decision gets revised in a meeting the document knows nothing about. The PRD does not update, because updating a document is manual work that competes with everything else and always loses. Within a week the PRD and the product disagree. Within a month everyone knows the PRD is stale, so nobody trusts it, so nobody reads it, so nobody keeps it current. The neglect is rational. Reading a document you know to be out of date is worse than not reading it, because it tells you confident, specific, wrong things.
This is the same rot that turns documentation into fiction, and it is worth naming plainly: any artifact that is disconnected from the work it describes decays, because nothing forces it to stay true. A PRD is the purest example. It is born disconnected. It lives in a doc tool, the work lives in the repo and the tracker, and the only thing linking them is your discipline, which does not scale.
The document is doing three jobs and none well
Part of why the PRD is unloved is that it is quietly asked to be three different things, and it is bad at all three at once.
- A decision record. What did we decide and why. But decisions made after the PRD is written never make it back in, so it captures the decisions from one day and silently misses the rest.
- A communication artifact. Getting everyone aligned. But alignment is a conversation, and a long static document is a poor substitute for one. People align in the discussion, then the document ossifies whatever state the discussion happened to be in.
- A build spec. What to actually construct. But it is prose, ambiguous by nature, and now an agent is reading it too, filling every gap with a confident guess.
Cramming all three into one artifact guarantees mediocrity at each. The decision record is stale, the communication is one-directional, and the build spec is ambiguous, which is the reason a running prototype makes a sharper spec than prose. And because it is one big document, fixing any one job means rewriting the whole thing, which nobody does.
What changes when agents read it too
For years the PRD’s ambiguity was survivable because a human engineer read it and filled the gaps with judgment and a follow-up question. The document could be sloppy because the reader was smart and would come ask you.
An agent does not come ask you. It reads the PRD, hits the same ambiguity, and resolves it silently with the most probable interpretation, which is often not yours. Then it builds. Fast. The vagueness a human would have flagged becomes a shipped feature that technically matches the words and misses the intent. The PRD nobody reads has become a worse problem: a PRD the agent reads too literally and too fast, with no one in the loop to catch the gap before it is code. When building got cheap and deciding got expensive, the loose artifact stopped being a minor annoyance and became the thing that ships the wrong product.
Replace the document with a living decision
The fix is not a better document. It is to stop treating the requirement as a document at all, and treat it as a living decision connected to the work.
Concretely, that means a few shifts:
- Small and addressable, not big and monolithic. A decision about one behavior, that you can reference, revise, and supersede on its own, instead of a fifty-section document where any change means republishing everything.
- Connected to the code and the evidence, not sitting beside them. The requirement points at the implementation that satisfies it and the check that proves it. When the code changes, you can see the requirement it touches. When the requirement changes, you can see what has to move.
- Alive, not snapshotted. Its current state reflects the current decisions, because updating it is part of the flow of work and not a separate documentation chore that competes for time and loses.
When the requirement is a small living thing wired to the code and the evidence, reading it stops being a favor. People consult it because it is where the current truth lives, not the truth as of three weeks ago. That is what a living spec looks like next to a static one, once you accept the document was the problem. The reason nobody read the PRD was never laziness. It was that the PRD was not worth reading, because it was not connected to anything and it was not true anymore.
This is how a feature factory forms
There is a straight line from unread PRDs to a feature factory. When the requirement is a dead document, the actual decisions live in Slack, in memory, in the heads of whoever was in the room. Nothing connects a shipped feature back to the decision that motivated it, so nobody can ask whether it did what it was for. The team just ships, because shipping is the only legible signal left. The unread PRD is not a symptom of the feature factory. It is one of the mechanisms that builds it, because it severs the link between intent and output that would otherwise let you tell productivity from motion.
Where PaellaDoc fits
This is why in PaellaDoc a requirement is not a document you write and abandon. It is a living artifact connected to the code that implements it, the decisions that shaped it, and the evidence that it works. When the code moves, the requirement it touches is visible. When a decision changes, the requirement reflects it. There is no separate document to keep in sync by hand, because the requirement lives in the same graph as the work, which is the only arrangement where staying current is cheaper than going stale.
Stop trying to write PRDs people will read. The best-written PRD in the world still goes stale the day after you publish it, because the problem was never the writing. Kill the dead document. Keep a living decision, close to the work, true right now. That one people read, because for once it is worth their time.
Frequently asked questions
Why does nobody read the PRD?
Not laziness, and not because it is too long. Nobody reads it because a PRD is finished the moment you write it and sits where the work does not live. Within a week it disagrees with the product; within a month everyone knows it is stale, so they stop trusting it. Reading a document you know is out of date is worse than not reading it.
Do product managers still write PRDs in the AI era?
The document, less and less. The job it did, more than ever. What changes is the artifact: a static PRD is now dangerous because an agent reads its ambiguity and resolves it silently with the wrong guess, then ships fast. The requirement still has to exist, but as a small living decision wired to the code and the evidence, not a snapshot nobody keeps current.
What should replace the PRD?
A living decision connected to the work, not a better document. Make it small and addressable, so you can revise one behavior without republishing fifty sections. Wire it to the code that satisfies it and the check that proves it, so a change on either side is visible. Keep it alive as part of the flow of work, so its current state is the current truth.
Why is an ambiguous PRD more dangerous with AI agents?
A human engineer read a vague PRD, filled the gap with judgment, and came back with a question. An agent does not. It resolves the same ambiguity silently with the most probable interpretation, often not yours, and builds it fast. The vagueness a person would have flagged becomes a shipped feature that matches the words and misses the intent, with no one in the loop to catch it.
