In the Software Development Lifecycle, what does the Logical Design phase involve?

The Logical Design phase in the Software Development Lifecycle (SDLC) is focused on refining and detailing the logical models that represent the system's functionalities and requirements. During this phase, the emphasis is on ensuring that the models accurately reflect what the users need from the system and how the components of the system should interact with one another in a logical manner.

Revising logical models to meet requirements is crucial because it ensures that the design aligns with user needs and business objectives. This phase typically involves creating data models, process models, and system architecture designs, which serve as a blueprint for the subsequent physical design and development phases. It also helps identify any necessary adjustments to the models before they are physically implemented, ensuring that all user requirements are effectively captured.

In this phase, the logical models serve as the foundation for translating user requirements into designs that developers will use, making it a pivotal step in creating a successful software solution. The work completed here directly influences how well the final software product will meet user expectations and perform in real-world scenarios.
