Program Evaluation and Review Technique

Definition

Program Evaluation and Review Technique (PERT) is a project management tool used to schedule, organize, and coordinate tasks within a project. It is a statistical tool that employs network analysis to quantify the time, resources, and risks associated with project completion.

5 Must Know Facts For Your Next Test

1. PERT was developed in the 1950s by the U.S. Navy to manage the Polaris missile program, a complex and high-priority project.
2. PERT uses three time estimates for each activity: optimistic, most likely, and pessimistic, to account for uncertainty and risk.
3. The PERT network diagram visually represents the sequence of activities, their dependencies, and the critical path.
4. PERT helps project managers identify potential bottlenecks, allocate resources effectively, and make informed decisions to keep the project on track.
5. PERT is commonly used in conjunction with other project management techniques, such as Critical Path Method (CPM), to provide a comprehensive approach to project planning and control.

Review Questions

• Explain how the Program Evaluation and Review Technique (PERT) is used in production and operations control.
  • PERT is a valuable tool for production and operations control as it helps project managers effectively plan, schedule, and monitor the various activities and tasks involved in a production process. By using PERT, managers can identify the critical path, allocate resources efficiently, and anticipate potential bottlenecks or delays. This allows them to make informed decisions, adjust the production schedule as needed, and ensure the timely and successful completion of the project.
• Describe how the three time estimates (optimistic, most likely, and pessimistic) used in PERT contribute to effective production and operations control.
  • The three time estimates used in PERT – optimistic, most likely, and pessimistic – help project managers account for uncertainty and risk in the production and operations process. The optimistic time estimate represents the best-case scenario, the most likely time estimate reflects the expected duration, and the pessimistic time estimate considers the worst-case scenario. By considering this range of possibilities, managers can better plan for contingencies, allocate resources accordingly, and make more informed decisions to mitigate potential delays or disruptions in the production and operations control process.
• Evaluate the role of the PERT network diagram in supporting effective production and operations control.
  • The PERT network diagram is a crucial tool for production and operations control as it provides a visual representation of the sequence of activities, their dependencies, and the critical path. By analyzing the network diagram, managers can identify potential bottlenecks, optimize resource allocation, and make strategic decisions to ensure the timely and efficient completion of the production process. The network diagram also facilitates communication and collaboration among team members, allowing them to understand the overall project structure and their respective roles in achieving the desired outcomes. Ultimately, the PERT network diagram is a valuable asset in supporting effective production and operations control by enhancing planning, decision-making, and coordination within the project.
