What can be the limitations of critical path scheduling?

This method is not suitable for working in practical situations as there will be reallocation of projects and activities often. Another limitation is that tales too much time to identify all activities and inter relate them, so this scheduling is not suitable for big projects and is complex. This method is activity based, so it does not allow people to track resources independently of the activities. This is not suitable for projects with lot of overlapping activates.

Explanation / Answer

The primary disadvantage of critical path scheduling is, as mentioned in this post, the inability to track the resources independently. Instead, the critical path is monitored in this method. The bottleneck of any project will depend on how the resources are loaded or overloaded. This is the reason why critical path scheduling does not work in practical situations in which the resources are often re-allocated across parallel activities. This reallocation changes activity completion time and disrupts the plan. Second, the time estimates of critical path method are deterministic i.e. it takes one fixed estimate for the activity durations instead of having statistical distributions attached to them. Finally, again as mentioned in the post, is the complexity. Note that even when for small projects, the CPM representation can be very complex. For large projects, it becomes very difficult to monitor.
