Choose an option
-
Asingle time estimate
-
Bdouble time estimate
-
Ctriple time estimate
-
Dnone of these
Answer
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.
