PERT time estimates: how many estimates does PERT require for each activity? According to the PERT (Program Evaluation and Review Technique) approach, identify the number of time estimates used to model activity duration uncertainty. Choose the correct option.

Difficulty: Easy

single time estimate
double time estimate
triple time estimate
none of these

Correct Answer: triple time estimate

Explanation:

ConceptPERT models activity duration uncertainty with three estimates: optimistic (a), most likely (m), and pessimistic (b). These combine to give the expected time and variance for network analysis.

Why tripleUsing three points better captures uncertainty than a single or double estimate, improving schedule risk analysis.
