What is pert formula?
PERT (Program Evaluation and Review Technique) is calculated using a Weighted Average. It is based on Beta Distribution. The Mean can be determined by the following formula. E_PERT=(O+P+4×M)/6. A 3-Point Estimation can be done using either Simple Average or PERT Formula.
What is the difference between PERT and CPM?
PERT deals with unpredictable activities, but CPM deals with predictable activities. PERT is used where the nature of the job is non-repetitive. In contrast to, CPM involves the job of repetitive nature. There is a demarcation between critical and non-critical activities in CPM, which is not in the case of PERT.
