Differentiate between PERT and CPM.
Understand the Problem
The question is asking for a comparison between PERT (Program Evaluation and Review Technique) and CPM (Critical Path Method). This involves explaining their definitions, key features, applications, and differences in usage within project management.
Answer
PERT handles uncertain activities with a probabilistic model; CPM handles well-defined activities with a deterministic model.
The final answer is that PERT focuses on planning and controlling uncertain activities using a probabilistic model, while CPM manages well-defined activities using a deterministic model.
Answer for screen readers
The final answer is that PERT focuses on planning and controlling uncertain activities using a probabilistic model, while CPM manages well-defined activities using a deterministic model.
More Information
PERT (Program Evaluation Review Technique) is often used when the exact duration of each task is uncertain, hence it uses a probabilistic approach. CPM (Critical Path Method), in contrast, is used for projects with well-defined tasks and uses a deterministic approach for planning.
Tips
A common mistake is to use PERT for projects where activity durations are well-known, which is more suitable for CPM.
