PERT considers optimistic, likely and pessimistic time, thereby adding an element of probability to the final figure one obtains. CPM takes only a single time for any task. This time typically would be the 'likely' time for the task. PERT e...

CPM/PERT or Network Analysis as the technique is sometimes called, developed along two parallel streams, one industrial and the other military. ... We are also now ready to compute the SLACK or TOTAL FLOAT, which is defined as the difference between the Latest Start and Earliest Start.

The difference between PERT and CPM is in the times for each activity or outcome. CPM simply takes the expected (usually average) time, PERT uses the best case, expected case, and worst case estimates to calculate the duration:

DIFFERENCES BETWEEN CPM & PERT 1. CPM is activity oriented i.e. CPM network is built on the basis of activities. Also result Of carious calculation are considered in terms of activities of the project. On the other hand, PERT is event oriented. ... There is no difference between float and slack. FLOAT refers to an activity...

[Archive] PERT vs. CPM scheduling Computer Programming ... Anyone know a good tutorial explaining the difference between PERT and CPM scheduling techniques? These are formal techniques for developing schedules for software engineering projects. Unfortunately my textbook doesn't explain these very well.

The Major Differences and Similarities between PERT and CPM ... Therefore, PERT is considered a probabilistic tool. In CPM, there is only one estimate of duration; that is, CPM is a deterministic tool. The second difference is that CPM allows an explicit estimate of costs in addition to time.

The major difference between CPM and PERT is that while CPM uses a single estimate of activity duration, PERT uses three, and assumes that time is a variable. The three times are the most likely time, an optimistic time, and a pessimistic time.
