The logical dependencies between tasks are defined using an activity network diagram that enables identification of the critical path.
Therefore, the duration of the tasks is often estimated through a weighted average of optimistic, normal, and pessimistic cases.
The critical chain method adds "buffers" in the planning to anticipate potential delays in project execution.
[3] Float or slack time in the schedule can be calculated using project management software.
Analyzing progress compared to the baseline schedule is known as earned value management.
