Resource Breakdown Structure
A resource breakdown structure (RBS) is a hierarchical representation of resources by category and type used to facilitate planning and controlling of project work.
Explanation
The resource breakdown structure organizes and classifies project resources into categories such as labor, materials, equipment, and supplies. Each descending level represents an increasingly detailed description of the resource until the information is small enough to be used with the work breakdown structure (WBS) for planning, monitoring, and controlling.\n\nThe RBS is an output of the Estimate Activity Resources process and is used throughout resource management. It helps ensure that all required resources are identified and that resource usage can be tracked by category. It also supports organizational learning by providing a consistent framework for resource classification across projects.\n\nThe RBS is distinct from the organizational breakdown structure (OBS), which organizes work packages by responsible department or team. Together, the RBS and WBS provide a comprehensive view of resource allocation across project deliverables.
Key Points
- •Hierarchical chart classifying resources by category and type
- •Output of the Estimate Activity Resources process
- •Facilitates resource tracking, planning, and control
- •Categories typically include labor, materials, equipment, and supplies
Exam Tip
Know the difference between RBS (resource breakdown structure), WBS (work breakdown structure), and OBS (organizational breakdown structure). Each organizes project information differently.
