How to Write a Product Requirements Document?

1. No fixed format, the shorter the better. Oppose using templates, it should vary by project.

2. Use charts and diagrams instead of text when possible. Whether it's RD, FE, or QA, humans prefer concise and intuitive expressions. Of course, use text when necessary for clarity, don't be constrained by methodology.

3. Don't speak for others. Don't write about "technical architecture", "test planning", or "user experience solutions" unless you want to fight alone.

4. Don't try to include everything in the PRD. Keep materials like requirement analysis process, operation planning, project progress tracking, and evaluation conclusions to yourself.

5. Never imagine that documents can replace necessary communication like internal reviews, project kickoff meetings, and design confirmations.
