The Critical Path for a project is that sequence of dependent tasks that have the largest sum of most likely durations. The critical path determines the earliest possible completion date of the project.
Tasks that are on the critical path cannot be delayed without delaying the entire project schedule.
The slack time available for any noncritical task is the amount of delay that can be tolerated between the starting time and completion time of a task without causing a delay in the completion date of the entire project.
For each path, sum the durations of all tasks in the path.The path with the longest total duration is the Critical Path.The critical path for a project is that sequence of dependent tasks that have the largest sum of most likely durations. The critical path determines the earliest completion date of the project.The slack time available for any noncritical task is the amount of delay that can be tolerated between the starting time and completion time of a task without causing a delay in the completion date of the entire project.
