What is Critical Path Analysis? Meaning.
Critical Path Analysis (CPA) is a type of network analysis planning
technique that is used to plan and manage complicated projects or business processes.
CPA is a form of network analysis used to decide the continuous
chain of operations critical to completion of a project or business process
by its scheduled completion date.
It was developed in the 1950s to manage large defense projects.
Applications of Critical Path Analysis
- Lay out all tasks that have to be completed as part of a complex project
- Basis for preparation of detailed schedules and resource planning
- Monitor the progress of goals
- Signal the need for remedial action in case of problems in the project. CPA shows diagrammatically the interrelations in sequence of all the activities in a project / business process in such a way as to highlight, which are critical for the due performance of the overall work.
Critical Path Analysis versus Gantt Charts
Advantages of CPA over Gantt Charts:
- CPA identifies tasks, which have to be completed on time
- CPA identifies tasks, which can be delayed without effecting the project completion time
- CPA identifies the minimum time required to finish a project
- CPA identifies which tasks one needs to focus on to speed op a project.
Disadvantages of CPA compared to Gantt Charts:
-
CPA charts has no timeline, so the relation of tasks to time is less obvious.
-
CPA charts are more difficult to understand (especially for beginners)
How to Perform a Critical Path Analysis. Drawing a CPA Chart

-
Determine the earliest start date
-
Determine the required time for each task
-
Determine which tasks can be run in parallel and which ones are sequential.
-
Plot the activities in a CPA Chart, representing their logical relations by symbols.
