Critical Path Method (CPM)
Reference model
The critical path determines the shortest time to complete the project.
About this model
A project management technique that outlines the critical path through a project, showing which tasks are critical and which have flexibility in scheduling.
Originator not stated.
How to read it
- Identify tasks and their durations.
- Map out dependencies between tasks.
What this does
Identifies the longest sequence of dependent tasks that determine the minimum project duration, helping managers prioritize tasks and allocate resources effectively.
When to use it
Use it when you need to understand the minimum time required to complete a project and identify critical tasks that could delay the project.
Not when: Do not use it for projects with uncertain task durations or where tasks are not clearly defined and interdependent.
What happens next
Consider using a Gantt chart for visualizing the project schedule and task dependencies.
