Writing a PRD: From Need to Buildable

The direct answer: a PRD answers the dev team's four questions — whose problem this solves, what it should look like, what is explicitly out of scope, and how success is measured. A clear PRD halves the back-and-forth during development.
The direct answer: a PRD answers the dev team's four questions — whose problem this solves, what it should look like, what is explicitly out of scope, and how success is measured. A clear PRD halves the back-and-forth during development.
The problem
- Who hits the problem, in which scenario, at what cost.
- Why now: the cost of not doing it, or the timing reason.
Goals and measurement
- Measurable goals: “reduce X% of repeated steps” beats “improve the experience”.
- The measurement method and its data source are written down — a goal without a data source is not a goal.
Boundaries and non-goals
- What this version explicitly does not do — the non-goal list prevents scope creep better than the feature list.
- Each non-goal gets one sentence of “why not” — so reviews stop relitigating it.
Open questions
- Undecided items listed with an owner and a deadline — open questions in the document are safer than in the developers' guesses.
