<ul data-eligibleForWebStory="true">Engineer-friendly PRDs excel in well-defined problem statements that focus on user needs and pain points, rather than specific solutions.Clear problem statements lead to innovative solutions and prevent wasted effort on irrelevant features, as seen in Intercom's approach.Include specifics like who is affected, what the difficulty is, and the impact to quantify the pain point and emphasize its importance.Use plain language over technical jargon for better understanding across all team members, following Amazon's PRFAQ format.PRDs should have acceptance criteria that define when a feature is considered done and successful, ensuring alignment on project completion.Clearly defined acceptance criteria prevent misunderstandings and ensure testable outcomes for all team members.Consider edge cases to anticipate less common scenarios and prevent bugs, crashes, and poor user experiences.Engineers appreciate when PRDs explicitly address edge cases, showcasing foresight and thorough planning.AI-powered tools like ChatPRD and Zibly.ai can enhance the PRD writing process, offering structured drafts and comprehensive coverage of requirements.Well-written PRDs save time, reduce confusion, and demonstrate thorough product planning to engineering teams, leading to better products.
