PRD Generator & Template

A PRD — product requirements document — is a short written artifact that explains what a product or feature is for, who it serves, what it should do, and how you will know it succeeded. A good PRD is the alignment tool between product, engineering, design, and stakeholders before substantial work begins.

A PRD focuses on the "what and why" — the user problem, goals, and constraints. A technical spec focuses on the "how" — architecture, schema changes, API contracts. An RFC (Request for Comments) is a proposal seeking feedback on a decision and can apply to either domain. Many teams produce all three for big initiatives, but for smaller features a single combined doc is usually enough.

As short as it can be while still aligning the team. For a small feature, one page is plenty. For a quarter-sized initiative, 2–4 pages. If a PRD is longer than that, the work is probably better split into smaller pieces — each with its own PRD. Length is not a quality signal; clarity is.

For trivial bugs, copy changes, and well-understood iterations on existing features, a PRD is overkill — a ticket or short Slack thread works better. Use a PRD when there is genuine cross-team alignment work to do, when scope is fuzzy, or when you need to capture decisions that future engineers will care about.

Usually the product manager, but designers and engineering leads often co-author for technical or design-heavy work. The author is the person responsible for keeping the document accurate as the work progresses; everyone affected should review.

Treat the PRD as a living artifact, not a contract. Update Open Questions as they get resolved, edit Goals if the team learns something during build, and add a "Decisions" log section to capture changes with the date and rationale. A PRD that gets stale is worse than no PRD — link it to the live work and prune it as you ship.
