What is the main purpose of a Work Breakdown Structure (WBS)?

### Why this is right A Work Breakdown Structure (WBS) is a hierarchical decomposition of a project or major activity into successive levels. It makes the project work visible in a structured form. ### The concept A WBS helps a team organize a large undertaking into smaller components that can be described, coded, and scheduled. It is a structure for breaking down work, not a requirements specification or a measure of product quality. ### The other options - **B. To measure the reliability of the completed software**: Reliability is a product attribute measured through software metrics, not the purpose of a WBS. - **C. To document only the final source code**: Source code documentation is not the WBS's defining function. - **D. To identify users' functional requirements**: Requirements work identifies system services; a WBS decomposes project work. ### Terms - **Hierarchical decomposition**: Breaking a whole into nested levels of smaller parts. ### Remember A WBS breaks project work into manageable levels.
