Question 1

How do I write a PRD engineers will actually read?

Accepted Answer

Keep it short, state the problem before the solution, and define 'done' as measurable acceptance criteria. A PRD nobody reads is worse than none because it creates false confidence that everyone agrees.

Question 2

What should a PRD include?

Accepted Answer

The problem and target user, one measurable definition of success, explicit non-goals, requirements written as given/then acceptance criteria, known edge cases, and honestly flagged open questions.

Question 3

How long should a product requirements doc be?

Accepted Answer

As short as possible while leaving no room for a wrong interpretation. The best PRDs get shorter as the team fills in details together — treat it as a conversation starter, not a contract.

Question 4

How do non-goals help a PRD?

Accepted Answer

Listing what you are deliberately not building stops scope creep more effectively than any deadline, and lets engineers make good calls when the spec misses a case.
