How to Create a PRD How to create a Product Requirements Document using the BMad Method

Use the prd workflow to create a strategic Product Requirements Document with Functional Requirements (FRs) and Non-Functional Requirements (NFRs).

When to Use This

  • Medium to large feature sets
  • Multi-screen user experiences
  • Complex business logic
  • Multiple system integrations
  • Phased delivery required

Prerequisites

  • BMad Method installed
  • PM agent available
  • Optional: Product brief from Phase 1

Steps

1. Load the PM Agent

Start a fresh chat and load the PM agent.

2. Run the PRD Workflow

*create-prd

3. Provide Context

The workflow will:

  • Load any existing product brief
  • Ask about your project scope
  • Gather requirements through conversation

4. Define Requirements

Work with the agent to define:

  • Functional Requirements (FRs) - What the system should do
  • Non-Functional Requirements (NFRs) - How well it should do it

5. Review the PRD

The agent produces a comprehensive PRD scaled to your project.

What You Get

A PRD.md document containing:

  • Executive summary
  • Problem statement
  • User personas
  • Functional requirements (FRs)
  • Non-functional requirements (NFRs)
  • Success metrics
  • Risks and assumptions

Scale-Adaptive Structure

The PRD adapts to your project complexity:

Scale Pages Focus
Light 10-15 Focused FRs/NFRs, simplified analysis
Standard 20-30 Comprehensive FRs/NFRs, thorough analysis
Comprehensive 30-50+ Extensive FRs/NFRs, multi-phase, stakeholder analysis

V6 Improvement

In V6, the PRD focuses on WHAT to build (requirements). Epic and Stories are created AFTER architecture via the create-epics-and-stories workflow for better quality.

Example

E-commerce checkout → PRD with:

  • 15 FRs (user account, cart management, payment flow)
  • 8 NFRs (performance, security, scalability)

Best Practices

1. Do Product Brief First

Run product-brief from Phase 1 to kickstart the PRD for better results.

2. Focus on "What" Not "How"

Planning defines what to build and why. Leave how (technical design) to Phase 3 (Solutioning).

3. Document-Project First for Brownfield

Always run document-project before planning brownfield projects. AI agents need existing codebase context.

Next Steps

After PRD:

  1. Create UX Design (optional) - If UX is critical
  2. Create Architecture - Technical design
  3. Create Epics and Stories - After architecture
