PERT is a three time estimate and gives more weightage toQuestion 3Answera.Optimistic timeb.Most likely timec.Pessimistic timed.Expected time

The PERT (Program Evaluation and Review Technique) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project. It involves three time estimates:

1. Optimistic time (O): the minimum possible time required to accomplish a task, assuming everything proceeds better than is normally expected.
2. Pessimistic time (P): the maximum possible time required to accomplish a task, assuming everything goes wrong (but excluding major catastrophes).
3. Most likely time (M): the best estimate of the time required to accomplish a task, assuming everything proceeds as normal.

The expected time (T) for each activity is calculated using the formula:

T = (O + 4M + P) / 6

So, PERT gives more weightage to the Most Likely Time (M).
