Most teams do not need another PRD template. They need a hard stop. Vague scope does not become expensive because nobody wrote documentation. It becomes expensive because nobody is willing to say what will not be built.
Scope creep rarely announces itself as scope creep. It shows up as a reasonable sentence.
"Can we also add invites?" "Should we include analytics?" "What about an admin dashboard?" "If we are already building this, we might as well add billing, export, and notifications."
None of those ideas are obviously wrong. That is why they are dangerous. Bad ideas are easy to reject. Good-but-not-now ideas are what turn a clear V1 into a slow, expensive project that never reaches the market.
The buyer does not want a PRD generator
A product manager with stakeholder pressure is not waking up thinking, "I need a document generator." An agency owner watching a fixed-fee project expand is not looking for prettier requirements. A technical lead staring at a vague handoff is not asking for more words.
They want the bleeding to stop.
They want the request turned into a boundary. They want a defensible answer to "why is this not in V1?" They want engineering to build from a decision, not from a conversation that can be renegotiated every week.
V1 gets five features. Everything else is a future decision.
Five is not magic. Five is useful because it forces tradeoffs early,
while the cost of changing your mind is still measured in minutes
instead of engineering weeks.
A five-feature cap changes the planning conversation. Without a cap, the team asks, "What else should this product do?" With a cap, the team asks, "What are the five things this product must do to prove the business case?"
Why five features works
That second question is harder. It is also the question that protects budget.
Five features is enough to define a real workflow. It is not enough to hide indecision inside a backlog. That tension is the point. If a feature cannot survive the top-five cut, it probably does not belong in the first build.
The goal is not to make the product smaller forever. The goal is to make V1 clear enough to ship, measure, and learn from before the roadmap eats the project.
