Identifying major deliverables, deciding if adequate cost estimates can be developed, and identifying tangible components of each deliverable are all part of which of the following?

Question

Options

• AWork breakdown structure
• BOrganizational breakdown structure
• CResource breakdown structure
• DBill of materials

• A
  71% (47)
• B
  9% (6)
• C
  5% (3)
• D
  15% (10)

Explanation

A (Work Breakdown Structure) is correct because the WBS is the project management tool specifically designed to decompose project scope into manageable components - it starts by identifying major deliverables, determines whether cost estimates are feasible at each level, and breaks deliverables down into tangible, measurable work packages.

B (Organizational Breakdown Structure) is wrong - an OBS maps work to organizational units/departments, not deliverables or cost estimation. C (Resource Breakdown Structure) is wrong - an RBS categorizes resources (people, equipment, materials) by type, not deliverables. D (Bill of Materials) is wrong - a BOM lists the components needed to manufacture a product; it's a procurement/manufacturing concept, not a project scope decomposition tool.

Memory tip: Think "WBS = What's Being Scheduled" - it answers what needs to be done by breaking the project into deliverables, which is exactly what cost estimation and tangible components are all about.
