What is a Resource Breakdown Structure (RBS) used for?

• A. To categorize project resources by type and resource category for planning and assignment.
• B. To schedule activities.
• C. To define risk owners.
• D. To estimate costs.

Answer: (B)

Resource Breakdown Structure is a hierarchical representation of the resources you’ll need for the project, organized by resource type (such as people, equipment, materials) and resource category. Its main use is to help you plan and assign resources efficiently: it makes it clear what resources exist, where they’re needed, and who or what will supply them. By laying out all resource requirements across the work packages, it supports estimating how many units of each resource are required, coordinating procurement or staffing, and ensuring responsibilities for resource management are clear. While accurate scheduling depends on activity sequencing and duration estimates, the RBS provides the essential resource data that informs that scheduling. It isn’t about defining risk owners or directly producing the project schedule, but it does underpin resource planning and allocation, which are foundations for a realistic schedule and cost estimates.
