WBS Dictionary

Posted on July 23, 2009 by


The WBS dictionary is the document that accompanies the WBS (Work Breakdown Structure) which further elaborates upon the individual components of the WBS. The WBS Dictionary is an output of the fourth edition PMBOK®’s Create Work Breakdown Structure process. Together with the WBS and Scope Statement, it composes the project’s Scope Baseline which becomes part of the Project Management Plan. The WBS Dictionary can include: code of accounts identifiers, description of work, responsible organization, list of schedule milestones, associated schedule activities, resources required, cost estimates, quality requirements, acceptance criteria, technical references, and contract information. If useful, the WBS Dictionary can contain additional information about the components as well. Also see the earlier posting of Create Work Breakdown Structure Process (posted February 27, 2009) and WBS (Work Breakdown Structure) (posted July 21, 2009).
