Most PRDs die in the same way: a product manager spends three days writing one, shares it in Slack, and never hears about it again. Engineers skim the first paragraph, check if there's a Figma link, and start building off assumptions.
The problem isn't discipline. It's format.
What Makes a PRD Useful
A useful PRD answers three questions in the first 30 seconds:
- What problem are we solving, and for whom?
- What does "done" look like?
- What are we explicitly not building?
Everything else is supporting context. If an engineer can't answer those three questions after scanning your doc for a minute, the PRD needs work.
My Structure
After iterating across multiple teams, here's the structure I've landed on:
- One-liner — the problem in a single sentence
- User story — who, what, why
- Success metrics — how we'll know it worked
- Scope boundary — what's in, what's out
- Open questions — what I don't know yet (honesty > completeness)
The key insight: engineers don't need a narrative. They need a decision log.
More on this soon. This post is a work in progress.
