This document discusses key concepts in project management including activities, predecessors, successors, concurrent activities, events, merges, bursts, and dummy activities. It outlines rules for drawing network diagrams and common errors. It then describes the Critical Path Method (CPM) and Program Evaluation and Review Technique (PERT) and how they are used to plan, schedule, monitor, and control projects. Examples of project types that use CPM and PERT are provided. The document also discusses crashing the project completion time by reducing critical path activities' durations at an increased cost.
