This template depicts a Critical Path Precedence Diagram, which is a key tool in project management used to illustrate task dependencies and the longest stretch of dependent activities. The diagram includes various nodes labeled with letters (A to I), each representing a specific task. The numbers within each node represent the earliest start time, the latest start time, the earliest finish time, and the latest finish time. This type of chart is extensively used in project planning and control to visualize the sequence of activities, identify the critical path, and calculate buffer times for tasks.
