What is a PRD?
A Product Requirements Document (PRD) is a detailed specification that translates business requirements into concrete product features and functionality. It serves as the bridge between business objectives and technical implementation, providing development teams with clear direction on what to build and how it should work.
Unlike a BRD which focuses on the why, a PRD focuses on the what and how, detailing every feature, interaction, and technical requirement needed to bring the product to life.
