Final answer:
The feasibility study in the SDLC is done in the Planning phase. It is crucial for assessing a project's viability before further resources are committed to it. It precedes the Analysis, Design, and Implementation phases.
Step-by-step explanation:
In the Systems Development Life Cycle (SDLC), the feasibility study is typically done in the Planning phase. This phase involves evaluating the project's potential for success and determining if it is worth pursuing, considering factors such as economic feasibility, legal feasibility, operational feasibility, and technical feasibility. A feasibility study ensures that the project is viable before committing significant resources and time to it.
During the Planning phase, several activities are undertaken, which include defining the scope of the project, assessing the current system, and establishing the project's objectives and constraints. The feasibility study is crucial in deciding whether to proceed with the project or not. It sets the foundation for the Analysis phase, where a detailed examination of the business needs is performed, followed by the Design phase, where the technical architecture and specifications are created. The Implementation phase comes afterward, where the actual development and integration of the system take place.
