Study Notes
Program Evaluation and Review Technique (PERT) and Critical Path Method (CPM)
- PERT and CPM are network-based project scheduling procedures used to plan and schedule projects.
Activities and Project Network
- Activities are specific jobs or tasks that are components of a project.
- Activities are represented by nodes in a project network.
- A project network is a graphical representation of a project that depicts the activities and shows the predecessor relationships among the activities.
Critical Path and Path
- A path is a sequence of connected nodes that leads from the Start node to the Finish node.
- The critical path is the longest path in a project network.
- Critical activities are the activities on the critical path.
Activity Timing
- Earliest start time is the earliest time an activity may begin.
- Latest start time is the latest time an activity may begin without increasing the project completion time.
- Earliest finish time is the earliest time an activity may be completed.
- Latest finish time is the latest time an activity may be completed without increasing the project completion time.
Forward and Backward Pass
- Forward pass: moving forward through the project network to determine the earliest start and earliest finish times for each activity.
- Backward pass: moving backward through the network to determine the latest start and latest finish times for each activity.
Slack and Activity Time
- Slack is the length of time an activity can be delayed without affecting the project completion time.
- Optimistic time is the minimum activity time if everything progresses ideally.
- Most probable time is the most probable activity time under normal conditions.
