, the resource breakdown structure (RBS) is a hierarchical list of resources related by function and resource type that is used to facilitate planning and controlling of project work.''Project Management Body of Knowledge (PMBOK Guide) – Fourth Edition'', page 145. Project Management Institute, 2008. The Resource Breakdown Structure includes, at a minimum, the personnel resources needed for successful completion of a project, and preferably contains all resources on which project funds will be spent, including personnel, tools, machinery, materials, equipment and fees and licenses. Money is not considered a resource in the RBS; only those resources that will cost money are included.Rad, Parviz F. ''Project Estimating and Cost Management'', page 33. Management Concepts, 2001.


Definition

Assignable resources, such as personnel, are typically defined from a functional point of view: "who" is doing the work is identified based on their role within the project, rather than their department or role within the parent companies. In some cases, a geographic division may be preferred. Each descending (lower) level represents an increasingly detailed description of the resource until small enough to be used in conjunction with the

(WBS) to allow the work to be planned, monitored and controlled.


Example

In common practice, only non-expendable (i.e., durable goods) resources are listed in an RBS. Example of hierarchies of resources:
1. Engineering
   1.1 Mr. Fred Jones, Manager
         1.1.2 Ms. Jane Wagner, Architectural Lead
         1.1.3 Software Design Team and Resources
               1.1.3.1 Mr. Gary Neimi, Software Engineer 
               1.1.3.2 Ms. Jackie Toms, UI Designer
               1.1.3.3 Standard Time Timesheet (timesheet and project tracking software)
               1.1.3.4 Microsoft Project (project scheduling)
               1.1.3.5 SQL Server (database)
         1.1.4 Hardware Architecture Team and Resources
               1.1.4.1 Ms. Korina Johannes, Resource Manager
               1.1.4.2 Mr. Yan Xu, Testing Lead
               1.1.4.3 Test Stand A
                       1.1.4.3.1 SAN Group A
                       1.1.4.3.2 Server A1
               1.1.4.4 Test Stand B
                       1.1.4.4.1 SAN Group B
                       1.1.4.4.2 Server B1
Both human and physical resources, such as software and test instruments, are listed in the example above. The nomenclature is a numbered, hierarchical list of indented layers, each level adds an additional digit representing. For example, the numeric labels (1.1, 1.1.2) make each resource uniquely identifiable.''Define Resource Breakdown Structure'', Project Team Blog, posted June 26,2012, http://www.projectteamblog.com/index.php/define-resource-breakdown-structure-rbs/

. Sometimes a PM Administrator is designated in larger project who will manage the Project tool itself. This field is called the Enterprise Resource Outline Code and it falls into one of two categories, RBS (resource field) and RBS (assignment field). These are high-level fields that require managers who know what these will be used for in terms of the organization.''RBS Fields'', Microsoft Office Support page, https://support.office.com/en-au/article/RBS-fields-5d08f8c1-be86-4ea7-b93e-27ba5112427b (retrieved 3/13/2015)
