4 Control Schedule Exercise Use the WBS developed in last lecture for the convertible bicycle to create a project time management plan. PMBOK 9 Working Example: Convertible Bicycle Project Program Evaluation and Review Technique (PERT) Wikipedia.org PERT System PERT Diagram Program Evaluation and Review Technique A network model that is used to schedule projects. PERT was developed for the US Navy s Polaris Project in the 9 s. Adapted as a tool for business managers. It has the potential to reduce both the time and cost required to complete a project.

5 PERT Diagram Types PERT Illustration Activity on node diagrams: Maybe more than one single start and end node Nodes represent activities Arrows indicate precedence Activity on arrow diagrams: One single start and one single end node Arrows represent activities Nodes indicate beginning/end of activities Activity on node Activity on arrow 6 Dummy Activities Critical Path Method (CPM) Sometimes it is needed to insert dummy activities, with duration zero, in order to maintain the clarity of the diagram and the precedence relationships between activities. In activity on arrow PERT diagrams, each activity must be uniquely identifiable by its start and end nodes. It is determined by adding the times for the activities in each sequence. CPM determines the total calendar time required for the project. If activities outside the critical path speed up or slow down (within limits), the total project time does not change. The amount of time that a non critical activity can be delayed without delaying the project is called slack time. 7 8 CPM Terminology CPM Computation ET: Earliest Time LT: Latest Time ES: Earliest Start LS: Latest Start EF: Earliest Finish LF: Latest Finish ST: Slack Time min 8 C ( 7 ) 8 max 9
