Good question.
The Beta distribution is a curve which enables us to identify the optimistic, most likely and pessimistic times, and calulcate the expected time. If the distribution is skewed (leans more to one side than another) this will have the effect of moving the expected value from the most likely time nearer to the optimistic or pessimistic time. If the calculation of the expected time is different from the most likely time, this will have an impact on the duration of an activity, and may change the critical path.
