In which phase of SDLC would system specifications be documented?

The requirements analysis phase of the System Development Life Cycle (SDLC) is where system specifications are documented. During this phase, analysts gather and define the detailed needs and expectations of the users and stakeholders. This involves collecting information through various methods such as interviews, surveys, and observation, and then translating it into a comprehensive set of specifications that outline what the system must achieve.

This documentation serves as a foundation for the subsequent phases of the SDLC, particularly the design phase, where the documented requirements are used to plan the system architecture and design. It is crucial because a well-documented specification ensures that the development team has a clear understanding of what needs to be built, which helps prevent misunderstandings and misalignment later in the project.

The design phase, maintenance phase, and implementation phase serve different purposes within the SDLC. The design phase focuses on how the system will be constructed based on the specifications. The maintenance phase comes into play after the system has been implemented and is concerned with ongoing support and modifications. The implementation phase involves coding and deploying the system as per the design specifications. Each of these stages relies on the clarity and completeness of the documentation created during the requirements analysis.
