1 OM480 Defining the Project Parameters – Work Breakdown Schedule (WBS) (With Material from the Text Authors)

2 Overview Scheduling Work Breakdown Structures (WBS) Precedence Relationships PERT/CPM Activity Networks

3 Scheduling Project = Problem scheduled for solution Requires: –Planning –Organizing –Coordinating –Directing –Controlling gninnalP drawkcaB Forward organizing, coordinating, directing, and controlling

4 Project Management Trade-Offs Performance Quality CostTime

6 Hierarchical Breakdown of the WBS 1 2 3 4 Project Deliverable Subdeliverable Lowest subdeliverable Cost account* Work package 5 Complete project Major deliverables Supporting deliverables Lowest management responsibility level Grouping of work packages for monitoring progress and responsibility Identifiable work activities LevelHierarchical breakdownDescription *This breakdown groups work packages by type of work within a deliverable and allows assignment of responsibility to an organizational unit. This extra step facilities a system for monitoring project progress

7 WBS – Key Terms Objectives: Logical division of project –“How much by when” –Tied to specifications Tasks: Specific outcomes related to Objective Activities: Individual actions within a Task –A desired result Input(s) Transformation Output

8 WBS - Process Break down Objectives to Tasks to Activities Strive for single input yielding single output Measurable by hours to days Present in hierarchical methods (trees) Rely on “doers” over “experts”

9 WBS - Precedence Sequencing of activities based on relationship(s) Categories –Technical Requirements Physical movements –Safety and Efficiency Separate from technical requirements –Policy/Preference Decisions Aesthetics, approvals, other considerations –Resource Constraints $, equipment, skills, time

13 Duration and Activities Effort is not duration –Time spent in actual “work” Duration lasts longer –Elapsed time from activity start to finish –Imagine “NFL two-minute warning” More on specific techniques in Chs 6-8 Realities of Duration Planning –Deliveries –Breakdowns/Repairs –Approvals
