Work Breakdown Structures (WBS).

• Very important topic – you can surely expect some questions on WBS, WBS dictionary, and work packages. 

• Definition: WBS is 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. 

• The WBS is finalized by assigning each work package to a control account and establishing a unique identifier for that work package from a code of accounts. 

• These identifiers provide a structure for hierarchical summation of costs, schedule, and resource information. 

• Control accounts are placed at selected management points in the WBS.
