Requirements are crucial for IT systems as they are based on the system's goals. The main outcome of the requirements process is getting approval from stakeholders for all specified requirements. The resulting document, the Solution Requirements Specification (SRS), outlines what the system should do, not how it will do it. Prototyping is an effective way to reduce risks in requirements development. Dynamic Systems Development Methodology (DSDM) helps teams quickly define high-level requirements. The Unified Development Process is a popular system development methodology. Requirements management tools help teams gather, track, and manage requirements efficiently.
