During what phase of SDLC are system specifications created?

During the Design phase of the System Development Life Cycle (SDLC), system specifications are created. This phase focuses on outlining how the system will meet the requirements identified in earlier phases. It involves detailing the architecture, interfaces, data structures, and other essential components that dictate how the system will function.

Creating system specifications is crucial because they serve as a blueprint for the subsequent Implementation phase, guiding developers in constructing the system according to the planned design. The specifications provide a clear framework that ensures all stakeholders have a mutual understanding of the system's expectations, constraints, and functionalities.

In contrast, the Implementation phase involves the actual coding and development of the system based on previously defined specifications. The Planning phase is where project goals, scope, and feasibility are assessed, but no detailed specifications are generated at this point. Meanwhile, the Maintenance phase occurs after implementation and focuses on updates, corrections, and enhancements to the system, rather than creating specifications.
