A functional requirement is a documented statement specifying what a system must do — a particular behavior, feature, or function it must perform, such as 'the system shall allow users to reset their password.' Business analysts and product managers write these during requirements gathering to guide developers and testers, distinguishing them from non-functional requirements like performance or security. They form the backbone of specifications, user stories, and acceptance criteria in software and systems engineering.
