Which activity is part of project planning for a project manager?

Identifying project tasks is a fundamental activity in project planning because it involves breaking down the overall project into manageable components. This process enables the project manager to outline the specific tasks needed to achieve the project's goals and milestones. Each task can then be assessed for time requirements, resource allocation, and dependencies, which are crucial for effective scheduling and project execution. By having a clear understanding of the tasks that need to be performed, the project manager can better manage resources, track progress, and mitigate risks throughout the project lifecycle.

In contrast, the other activities mentioned, such as performing user training, developing software, and finalizing documentation, occur at different stages in the project lifecycle. They are important components of project execution and closure but do not fall under the initial planning phase where outlining and identifying tasks take precedence. Therefore, identifying project tasks is essential for laying the groundwork necessary for a successful project.
