What would you write in a PRD?
Explain the sections you would include, the decisions each section should support, and how you would distinguish essential requirements from implementation details. Describe how you would incorporate user needs, define measurable outcomes, document trade-offs, and align design, engineering, and business stakeholders. Be prepared to explain how you would keep the document actionable as assumptions change.
