What is the main goal of the systems design phase in an SDLC model?

The main goal of the systems design phase in the Software Development Life Cycle (SDLC) model is to create a physical model that meets all documented requirements. This phase involves translating the specifications gathered during the requirements analysis into a blueprint for building the system.

During systems design, various aspects such as the architecture, interfaces, data structures, and modules are defined. This detailed design is essential because it guides developers in implementing the system accurately, ensuring that all user requirements are met and that the system performs as intended. By focusing on creating a comprehensive design that encompasses both functional and non-functional requirements, the design phase sets the foundation for successful system development.

In contrast, testing functionalities is part of a later phase, typically referred to as the testing phase, where the created system is evaluated to ensure it behaves correctly. Gathering user feedback primarily occurs during earlier phases, particularly during requirements gathering and later during user acceptance testing, where systems are validated against user needs. Releasing the final product happens at the end of the SDLC, after development and testing are complete, marking the transition from development to operational use.
