An optimistic estimate is the minimum time in which an activity or task can be completed. This is a best-case scenario where everything goes well and there is little or no chance of finishing earlier. A most likely estimate, as the name implies, is the normally expected time required to complete the task or activity. A pessimistic estimate is a worst- case scenario and indicates the maximum time the activity can take.
Thus, while AON is a network diagramming tool, PERT is a time estimation tool. Both tools are used to together to find the critical path and estimate the maximum time required to complete the project in project scheduling.
