Problem — who, what, why now, how painful
Success metric — how we'll know we won
Proposal — the solution at the right altitude, not code
Scope — what's in, what's out, what's later
Open questions — known unknowns, explicitly listed
Appendix — research links, data, mocks, tradeoffs
5 Rules
Lead with the problem, not the solution
Short > long — engineers won't read 20 pages
Link-heavy — data, research, mocks live elsewhere
Update it — PRDs drift; stale PRDs are landmines
Write for the skim — headings, bullets, TL;DR at top
FAQ
Are PRDs still relevant or have docs like RFCs replaced them?
Still relevant, but lighter. Modern PRDs are 1–3 pages with links to deeper docs, not 20-page tomes. Some orgs use RFCs (engineering-led) for technical decisions and PRDs (PM-led) for product decisions. The best PMs pick whatever format their team reads and updates.
