Work Packages: Division of Tasks Work Units: Division of Work Packages Project Management:
The science and art of achieving the Requirements within predetermined Time and Resource parameters.
Project Management Activities: Planning-Objectives Resources Work Break-down Structure Organization Scheduling- Project Activities, Start & End Times, Activity Network Controlling-Monitor, Compare, Revise, Action Work Breakdown Structure: WBS is a hierarchical decomposition of the project into phases, deliverables and work packages. 1.Project 2. Major Tasks in the project 3. Subtasks in the major tasks 4.Activities (or “work packages”) to be completed Project Controlling: Close monitoring of Resources, Costs, Quality, Budgets. Feedback enables revising the Project Plan and Shift Resources. Computerized tools produce extensive reports Six Steps PERT & CPM: 1. Define the Project and prepare the Work Breakdown Structure 2. Develop relationships among the activities - decide which activities must precede and which must follow others 3. Draw the network connecting all of the activities 4. Assign Time and/or Cost Estimates to each activity 5. Compute the longest time path through the network – this is called the Critical Path 6. Use the network to help Plan, Schedule, Monitor, and Control the project Perform a Critical Path Analysis: The Critical Path is the Longest Path Through the Network
The Critical Path is the Shortest Time in which the Project Can Be Completed. Any delay in Critical Path activities delays the project. Critical Path Activities have no slack time Variability in Activity Times: CPM assumes we know a fixed time estimate for each activity and there is no variability in activity times PERT uses a Probability Distribution for Activity Times to allow for Variability.
