Which of the following is NOT a step in the SDLC?

In the context of the Systems Development Life Cycle (SDLC), the primary stages typically include planning, analysis, design, implementation, testing, deployment, and maintenance. Each of these stages plays a critical role in the successful development and deployment of information systems.

While feasibility analysis, system design, and system testing are all integral components of the SDLC, project execution is not formally recognized as a distinct step within this methodology. The activities associated with project execution, such as coding or implementation, are usually part of the broader implementation phase rather than a separate step.

Understanding the specific terminology and structure of the SDLC is essential for clearly delineating the responsibilities and expectations throughout the development process. Recognizing what constitutes a proper phase in the cycle helps ensure that projects are effectively planned and executed, leading to better management of resources and outcomes.
