What is a PRD? A Complete Guide for Modern Development


What is a PRD?


A Product Requirements Document (PRD) is a document that outlines what you're building, why you're building it, and how it should work. It serves as the blueprint for your project.


Why PRDs Matter


Even in the age of AI-assisted coding, PRDs remain essential. They provide:


  • **Clarity** - Forces you to think through your product before writing code
  • **Direction** - Gives AI assistants clear instructions
  • **Alignment** - Keeps everyone (including AI) on the same page
  • **Reference** - A document to return to when questions arise

    • Traditional vs Modern PRDs


    Traditional PRDs were lengthy documents written by product managers for engineering teams. Modern PRDs, especially for AI-assisted development, are different:


  • **Shorter** - Focus on what matters
  • **Structured** - Easy for AI to parse
  • **Technical** - Include implementation guidance
  • **Living** - Updated as the project evolves

    • Key Components


    A good PRD includes:

  • Product overview and goals
  • Target users and use cases
  • Feature requirements
  • Technical specifications
  • Constraints and considerations
