Which stage is NOT part of the project development lifecycle?

The project development lifecycle typically includes a series of stages that guide a project from initiation to completion. These stages commonly encompass the concept, development, and implementation phases.

The concept phase is where ideas are generated, defined, and scoped. The development phase involves creating the necessary designs and plans to meet the project objectives. The implementation phase is where actual project work takes place, translating the plans into tangible results.

Evaluation, while important in assessing the project's outcomes and overall performance, is generally not considered a distinct stage of the project development lifecycle. Instead, evaluation may occur both during and after the project implementation stage to inform improvements and learnings for future projects. It is more often viewed as a part of project monitoring and review processes rather than a standalone phase in the lifecycle.

Thus, categorizing evaluation as a stage implies a misunderstanding of how it fits within the development lifecycle, which is why it is the option that stands apart from the others.
