CPM Method Development Explained
The Critical Path Method (CPM) is a fundamental project management technique. It is designed to help project managers identify the sequence of tasks that directly impact the project's completion time. Tasks lying on this sequence are called 'critical tasks', and the sequence itself is the 'critical path'. Any delay in these critical tasks directly delays the entire project.
Critical Path Method Origin
The CPM technique was pioneered and developed by J. E. Kelly and M. R. Walker. They were working for the DuPont company in the United States during the late 1950s. Their objective was to find a better way to manage the complex maintenance schedules and construction projects undertaken by the company.
CPM Pioneers vs. Other Figures
While other individuals listed are significant figures in project management and related fields, they are not credited with the initial development of the CPM method:
- H. L. Gantt: Famous for the Gantt chart, which visually represents project schedules, but this predates the network-based CPM.
- Kelly and Walker: The correct developers of the CPM method.
- G. Keller: Known for contributions to operations research, but not the primary developer of CPM.
- B. Taylor: Frederick Winslow Taylor is recognized for scientific management principles, focusing on work efficiency, not the critical path analysis technique.
Understanding CPM Developers
In summary, the development of the Critical Path Method (CPM) is attributed to the innovative work of Kelly and Walker at DuPont.
