Which phase of the SDLC focuses on defining the detailed system requirements?

The phase of the Systems Development Life Cycle (SDLC) that focuses on defining the detailed system requirements is indeed the requirements gathering or analysis phase. During this critical phase, stakeholders, including users and project sponsors, collaborate to identify and document the specific needs and expectations for the system. This involves eliciting information through techniques such as interviews, surveys, and workshops, and subsequently analyzing this information to produce a comprehensive set of requirements that will guide the development of the system.

This phase sets the foundation for all subsequent phases of the SDLC, as the detailed requirements inform both the design and implementation of the system. Without a clear understanding of what the system should accomplish, it would be challenging to design a solution that meets the users’ needs or to effectively test it later on. The other phases, such as design, implementation, and testing, are built on these well-defined requirements, making this phase crucial for the success of the overall project.
