4Scope Baseline Contains three elements Scope Statement WBS WBS Dictionary
5The WBS “Provides a vision of what has to be delivered” The process of subdividing project deliverables and project work into smaller, more manageable components.Deliverable-oriented hierarchical decomposition
6Key WBS Definitions PMBOK 5th Ed. p. 125/6 “Work” refers to products or deliverables that are the result of activities, not the activities themselves.The Scope Baseline (which includes the WBS) is an input to schedule development (not the other way around).
7What Makes a “Quality” WBS? “Project activities are not listed, as these are components of the project schedule, not the WBS.”“All (WBS) elements are nouns. Verbs are not use to identify WBS elements.”(Schedule activities are written with the verb/object sentence structure – from the PMI Scheduling practice standard)From PMI WBS Practice Standard, 2nd Ed., Section 5.5.1

17How Much Detail in the WBS? From PMBOK5 22.214.171.124 Deciding on a Work Package levelSome deliverables need to be decomposed only to the next levelOthers need additional decompositionAs work is decomposed to greater levels, the ability to plan, manage and control the work is enhancedUse your judgment
18How Much Detail in the WBS? From PMBOK5 Section 126.96.36.199 Excessive Decomposition leads toNon-productive management effortInefficient use of resourcesDecreased efficiency
19How Much Detail in the WBS? From PMBOK5 Section 188.8.131.52 Premature DecompositionThere may be insufficient information about elements that will not be worked until far in the futureWait until the WBS element is sufficiently understood to plan and decompose itUse Rolling Wave Planning
20The WBS is NOT a Schedule This is not a WBS. This is a numbered schedule:Project Activities do not belong in the WBS.The WBS consists of nouns, not verbs.The WBS (as part of the Scope Baseline) is an input to the schedule development processes, not an output.
