To facilitate detailed planning and resource allocation, a project manager wants to break down the project objectives into quantifiable components. Which of the following tools should the project manager use?
A risk register
A resource assignment matrix
A communication plan
A work breakdown structure
The correct answer is a Work Breakdown Structure (WBS). A WBS is a hierarchical decomposition of the total scope of work into smaller, manageable parts. It helps the project manager and team estimate costs, allocate resources, and schedule activities more accurately. A resource assignment matrix outlines roles and responsibilities but does not break down project objectives into components. A risk register is used to document identified risks and their responses. A communication plan outlines how project information will be shared but does not assist in breaking down project objectives.
