Which of the following are phases in the systems development lifecycle (SDLC)?

The correct choice identifies one of the essential phases in the systems development lifecycle (SDLC). The design phase is crucial as it involves defining the system’s architecture, components, modules, interfaces, and data to fulfill specified requirements. During this phase, the details of how the system will meet user requirements are articulated, and various methodologies and design principles are applied to create a blueprint for the system.

In the SDLC, each phase serves a unique purpose and builds upon the previous one to ensure a successful project outcome. For example, planning establishes the project vision and scope, while deployment and feedback play roles in implementing the system and evaluating its performance post-launch. Design stands out as the phase where abstract ideas transition into concrete specifications that guide developers in building the software.

Recognizing the importance of the design phase is crucial for understanding the overall framework of the SDLC, and it emphasizes how critical this step is in reducing risks and ensuring that the final product meets quality standards and user expectations.
