The project manager is engaging in the process of creating a Work Breakdown Structure (WBS). This involves subdividing the project deliverables and project work into smaller, more manageable components, known as work packages. The WBS is a deliverable-oriented hierarchical decomposition of the work to be executed by the project team, which is essential for detailed project planning, assigning responsibilities, and tracking project progress.
