Final answer:
The correct statement about the WBS is that it is deliverable-oriented. It breaks down the project into smaller parts focused on creating specific outcomes, and it is not the same as a Bill of Material or an Organizational Breakdown Structure.
Step-by-step explanation:
The Work Breakdown Structure (WBS) is a key project management tool that is used to break down a project into smaller components or 'work packages.' It forms a hierarchical decomposition of the total scope of work to be carried out by the project team to accomplish the project objectives and create the required deliverables. Therefore, the true statement about the WBS is a. The WBS is deliverable-oriented, which means it focuses on breaking down the project into manageable pieces that can deliver tangible outcomes or products.
Option b is incorrect because the WBS is not an unstructured list, but rather a structured representation of a project's work. Option c is also incorrect because the WBS is different from an Organizational Breakdown Structure, which organizes project team members according to the work they specialize in or the functions they perform. Lastly, option d is not true because the WBS refers to project deliverables, not a Bill of Material (BOM), which is a detailed inventory of the items and materials required to construct a product.
