This skill helps write structured Product Requirements Documents (PRDs) using industry-standard frameworks.

• Value-Complexity Matrix
• MVP scope definition

4. Success Metrics#

• North Star Metric
• Key Results

Usage Examples#

Example 1: New Feature PRD User: "Help us write a PRD for the user login feature" → Output: A complete PRD including problem statement, user stories, requirement prioritization, and success metrics

Example 2: Product Iteration PRD User: "Need to define product requirements for shopping cart optimization" → Output: A structured PRD focused on shopping cart optimization, including user journey and acceptance criteria

Example 3: Documenting Product Decisions User: "Document our decision to abandon the social sharing feature" → Output: Product decision document including background, analysis, and decision outcome

Notes#

• PRDs should be clear and actionable; avoid vague language
• Requirement prioritization should align with business objectives
• Success metrics should be quantifiable and trackable
• Acceptance criteria should be specific and testable
