PRD

Motivation

A PRD converts a business need into a shared description of what a product or feature should accomplish for users. It aligns product, design, engineering, QA, operations, and stakeholders before implementation diverges.

Typical contents

• Product context and target users
• Problem statement and desired outcomes
• User journeys, use cases, and user stories
• Functional and non-functional requirements
• Acceptance criteria
• UX references or interaction notes
• Dependencies, constraints, milestones, and risks
• Success metrics and release considerations

Naming note

PRD most commonly means Product Requirements Document. Some organizations use “Project Requirements Document”; teams should define their local terminology and avoid assuming every company uses the acronym identically.

Relationship to other documents

The BRD explains the business need. The PRD defines expected product behavior. The SDD describes the design that satisfies those expectations, and the TSD gives implementers precise technical instructions.

Common mistakes

• Writing implementation decisions as product requirements.
• Listing features without explaining the user problem.
• Omitting non-functional requirements and operational constraints.
• Treating acceptance criteria as a substitute for broader product context.
