Multiple Choice QuestionPERT uses ____ for each activity.Multiple choice question.three time estimatesfour time estimatesone time estimatetwo time estimates

Break Down the Problem

1. Identify the purpose of PERT (Program Evaluation and Review Technique).
2. Understand the number of time estimates used in PERT calculations.

Relevant Concepts

1. PERT is a project management tool that emphasizes time management.
2. It typically involves three time estimates: optimistic, pessimistic, and most likely.

Analysis and Detail

1. The three time estimates are defined as follows:
   • Optimistic Time (O): The minimum possible time required to complete the activity, assuming everything proceeds better than expected.
   • Pessimistic Time (P): The maximum possible time needed, assuming everything goes wrong.
   • Most Likely Time (M): The best estimate of the time required, assuming normal problems and opportunities.

Verify and Summarize

The correct option, given the purpose of PERT, is that it uses three time estimates.

Final Answer

The correct choice is: three time estimates.
