Business Requirements Document (BRD)
A formal written agreement between a business sponsor and the delivery team that captures the business need, project scope, stakeholder requirements, functional specifications, and acceptance criteria.
Full Definition
A Business Requirements Document (BRD) is a structured deliverable produced during the requirements phase of a project. It translates business goals and stakeholder needs into a specification that engineers, designers, and QA teams can act on. A well-written BRD eliminates ambiguity, prevents scope creep, and creates a shared understanding of what success looks like before a single line of code is written.
