The document discusses the critical path method (CPM) for project planning. CPM involves breaking a project into individual tasks and activities, identifying their dependencies, estimating durations, and determining the critical path of longest-running activities that must finish on time for project completion. It helps managers schedule work, allocate resources, and manage risks systematically. The document also outlines benefits like reduced delays and improved organization, as well as limitations such as potential for delays and reduced flexibility. Key CPM steps include specifying activities, establishing sequences, creating network diagrams, estimating activity times, identifying critical paths, and using critical path diagrams to track project progress.
