Which method is NOT typically associated with the software development lifecycle?

The method that is not typically associated with the software development lifecycle is execution. In the context of software development, the lifecycle commonly encompasses phases such as planning, design, implementation, testing, deployment, and maintenance. Each of these phases contributes to the structured approach needed to create software products effectively.

Execution, while it might imply the running of software, is not specifically defined as a separate phase in the lifecycle models like Waterfall, Agile, or similar methodologies. Instead, execution is often an outcome or part of the implementation and deployment phases where the software is actually operated by users. By understanding the standard phases of the software development lifecycle, it becomes clear why execution does not fit as a distinct method within this framework.
