How to Write PRDs for Product Managers
Clarity Over Complexity
Use plain language. Product development already carries enough jargon. A PRD filled with buzzwords forces readers to decode meaning before they can absorb it. Write the way you There is a temptation in professional writing to equate length with rigour and complexity with intelligence. A long, dense document feels thorough. It feels like evidence of serious thinking. Product managers new to PRDs fall into this trap constantly, and experienced ones return to it whenever they feel uncertain about a decision and compensate by writing more.
Resist it entirely.
The measure of a well-written PRD is not how much it contains. It is how quickly a designer, an engineer, or a stakeholder can read it and understand exactly what is being built, why, and for whom. Every sentence that does not serve that understanding is a sentence working against the document.
Clarity is a discipline, not a default. Here is what it looks like in practice.
would explain the feature to a thoughtful colleague who has context but not expertise in your specific domain. If a sentence requires a second reading to understand, it needs to be rewritten before it enters the document.
Be specific, not approximate. This is where most clarity failures live. Words like seamless, intuitive, fast, appropriate, and user-friendly feel meaningful when you write them. They are not. Each reader fills them in with their own interpretation, and those interpretations diverge in ways that surface as conflict during development.
- Not the feature should feel fast but the page must load within two seconds on a standard broadband connection
- Not the form should be easy to complete but users must be able to complete the form in under three minutes without accessing help documentation
- Not error messages should be helpful but error messages must state specifically what went wrong and what the user should do next
One idea per statement. Compound requirements that bundle multiple behaviours force readers to untangle meaning before they can act on it. Each statement should do one job. Each requirement should describe one behaviour. Each section should answer one question.
Cut what does not need to be there. Background that does not change how the team will build the feature should be shortened or removed. Context that every team member already has does not need to be restated. Respect the reader's time and the document will be trusted. Waste it and the document will be skimmed, which is worse than not being read at all because it creates the illusion of alignment without the substance of it.
Clarity is not a style preference. It is a functional requirement of the document itself. A PRD that is hard to read is not a thorough PRD. It is an unfinished one.
