Network Diagram With A Critical Path
Free Printable Network Diagram With A Critical Path
First developed by the united states navy in 1958 it is commonly used in conjunction with the critical path method cpm that was introduced in 1957.
Network diagram with a critical path. It calculates the project the longest time for completion. The critical path is the longest path of the network diagram. In case if the project management needs to accelerate the project the times for critical path activities should be reduced. This s because the critical path cp activities show the longest path of the project to finish and therefore any activity on the critical path will have zero floats.
The program or project evaluation and review technique pert is a statistical tool used in project management which was designed to analyze and represent the tasks involved in completing a given project. The critical path method uses a project network diagram similar to the precedence network diagram. The activities in the critical path have an effect on the deadline of the project. When there s a delay on a critical path cp activity it will cause project delays respectively.
Calculating critical path for a network diagram task 1 4 days task 2 5 days task 3 3 days task 4 7 days task 5 4 days identify tasks durations dependencies. Find out the length of all the paths in the network diagram the longest path is the critical path float ef lf es ls. If an activity of this path is delayed the project will be delayed. Once you have all of the necessary activities worked out and added to the diagram you can use the critical path method in project management to find the optimal way to finish those tasks.
