Lecture Project management in practice (Fifth Edition) – Chapter 5: Scheduling the project. The following will be discussed in this chapter: Pert and CPM networks, project uncertainty and risk management, simulation, the gantt chart, extensions to PERT/CPM. | Chapter 5 Scheduling the Project Introduction Project schedule is the project plan in an altered format It is a convenient form for monitoring and controlling project activities Can be prepared in several formats Gantt charts PERT network CPM network PERT and CPM Networks PERT and CPM developed independently in 1950’s Program Evaluation and Review Technique (PERT) . Navy, Booz-Allen Hamilton, and Lockheed Aircraft Probabilistic activity durations Critical Path Method (CPM) Dupont De Nemours Inc. Deterministic activity durations The Language of PERT/CPM Activity A task or set of tasks Uses resources and time Event An identifiable state resulting from completion of one or more activities Consumes no resources or time Predecessor activities must be completed Milestones Identifiable and noteworthy events that mark significant progress The Language of PERT/CPM Continued Network A diagram of nodes (activities or events) and arrows (directional arcs) that illustrate the technological . | Chapter 5 Scheduling the Project Introduction Project schedule is the project plan in an altered format It is a convenient form for monitoring and controlling project activities Can be prepared in several formats Gantt charts PERT network CPM network PERT and CPM Networks PERT and CPM developed independently in 1950’s Program Evaluation and Review Technique (PERT) .

Mostly AON used throughout this textbook AON used by most of the popular software AON networks are easier to draw by hand Large (20+ activities) AOA networks are .
