The PERT estimation procedure uses pessimistic, most likely, and optimistic estimates of the activity time to obtain the expected value and the standard deviation for each activity. The standard deviation is required only if the analyst wishes to make probability statements about completing the project by a certain date. Using the inputs listed 1. Create the network diagram using the PERT method to calculate the estimated duration for each activity: 2. Calculate the critical path; 3. Calculate the minimum expected time in which the project can be completed; (5 m 4.
