Question #: 39
Topic #: 4
You are the project manager for your organization. You are working with your project team to create activity duration estimates using the PERT method. What is the formula for PERT?
PERT, which means the Program Evaluation and Review Technique, is a duration estimating technique that uses the formula (O+(4M)+P)/6 for the optimistic, most likely, and pessimistic values for each work package. A PERT chart is a project management tool used to schedule, organize, and coordinate tasks within a project. PERT stands for Program Evaluation Review Technique, a methodology developed by the U.S. Navy in the 1950s to manage the Polaris submarine missile program. A PERT chart presents a graphic illustration of a project as a network diagram consisting of numbered nodes (either circles or rectangles) representing events, or milestones in the project linked by labeled vectors (directional lines) representing tasks in the project. The direction of the arrows on the lines indicates the sequence of tasks.
Answer option C is incorrect. This is the formula for the three-point estimate.
Answer options A and B are incorrect. These are not the valid formulas.
