In PERT chart, the activity time distribution is Correct Answer Beta

Explanation:

CPM does not directly model uncertainty.

PERT was developed to address the needs of projects which are being done for the first time – a challenge to estimate activity duration.

PERT (Program Evaluation and Review Technique) uses 3 cases:

  • Most Optimistic
  • Most Pessimistic
  • Most likely durations

 

PERT determines the probability for each duration, whereas CPM considers the most likely duration.

In the standard PERT analysis, the distribution assumed for the activity times is a Beta distribution.
