What each part should cover
Section-by-section guide
Goals
Explain what decision this section helps the team make and how success will be recognized.
Users
Name the people involved, what they need, and what they are responsible for approving or using.
Features
Describe the features clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.
Flows
Describe the flows clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.
States
Describe the states clearly enough that a founder, teammate, or AI agent can use it without needing hidden context.
Acceptance checks
Make the standard observable so the team can review, approve, or reject the output without guessing.
Practical workflow
How to create and use it
- 01Convert BRD objectives into product goals and user outcomes.
- 02Define features, flows, screens, states, roles, and data requirements.
- 03Review scope with design, engineering, and business stakeholders.
- 04Use the PRD as the source for design system, technical architecture, SOW, and sprint planning.
Copy into your workspace
Starter template
- 01State the product goal and the first release outcome.
- 02Define users, workflows, features, states, and non-goals.
- 03List data, permissions, integrations, analytics, and risks.
- 04Add acceptance criteria for every must-have capability.
Make the draft usable
Weak vs strong examples
Feature requirement
Weak
Users can upload files.
Strong
Client admins can upload PDF, DOCX, PNG, and CSV files up to 50MB, see upload progress, retry failed uploads, and receive validation errors before submission.
Acceptance criteria
Weak
Upload should work properly.
Strong
Given a valid file under 50MB, when the user uploads it, the file appears in the project document list with uploader, timestamp, status, and preview action.
How to know it is useful
Quality checklist
- 01Every key feature has user value, priority, behavior, states, and acceptance criteria.
- 02The PRD includes non-goals and edge cases, not only happy paths.
- 03Design and engineering can estimate from it without guessing core behavior.
- 04Open questions are visible and assigned.
Before you hand it off
Document readiness checklist
- The product requirements document has a named owner and approval path.
- The business or product decision this document supports is explicit.
- Inputs, assumptions, and open questions are separated from confirmed facts.
- Scope boundaries and non-goals are clear enough to prevent silent expansion.
- The document can be handed to a teammate, agency, or AI agent without hidden context.
- Every key feature has user value, priority, behavior, states, and acceptance criteria.
- The PRD includes non-goals and edge cases, not only happy paths.
- Design and engineering can estimate from it without guessing core behavior.
Generate the first draft
AI prompt
Create a Product Requirements Document from this business brief. Include product goals, users, use cases, features, priorities, workflows, page inventory, roles, permissions, data model, integrations, states, edge cases, analytics, acceptance criteria, risks, and open questions. Make it suitable for design, engineering, and AI-agent handoff.
Avoid these
Common mistakes
- Writing a PRD as a marketing brief.
- Missing empty, loading, error, permission, and failure states.
- No prioritization or release boundary.
- Unclear roles, data model, or integration assumptions.
Use this after the draft
Handoff assets
- Feature list and priorities
- User flows and page inventory
- State and acceptance criteria checklist
- Engineering and design questions
