WebbCritical Path Analysis and PERT are powerful tools that help you to schedule and manage complex projects. They were developed in the 1950s to control large defense and technology projects, and have been used routinely since then.

There are three times estimates in PERT, i.e. optimistic time (to), most likely time ™, pessimistic time (tp). On the other hand, there is only one estimate in CPM. PERT technique is best suited for a high precision time estimate, whereas CPM is appropriate for a reasonable time estimate. gemwoods collection
