What is the Critical Path Method (CPM)?
- The Critical Path Method (CPM) is a project management tool used to identify the longest sequence of dependent tasks in a project.
- This sequence, known as the critical path, determines the shortest time required to complete the project.
The critical path is the sequence of tasks that cannot be delayed without affecting the project's overall completion time.
How Does the Critical Path Method Work?
1. Critical Path Diagram
- A critical path diagram is a visual representation of project tasks and their dependencies.
- It helps identify which tasks must be completed before others can begin.
Use arrows to show dependencies between tasks, making it easier to track the sequence.
NoteSome tasks, like testing, can only start after the prototype is developed.
2. Identifying the Critical Path
- To find the critical path, you need to determine the longest sequence of dependent tasks.
- This sequence represents the minimum time required to complete the project.
Tasks on the critical path always have zero float.
