Which method uses estimates to plan and coordinate project activities?

• A. Waterfall method
• B. Harmonogram
• C. Program Evaluation and Review Technique
• D. Chaos engineering

Answer: (C)

The main idea here is planning work by using estimates to map out the order and timing of activities. The Program Evaluation and Review Technique does this by collecting three time estimates for each task—optimistic, most likely, and pessimistic—and turning them into an expected duration. With those durations, you build a network of task dependencies, which shows how work must flow and where delays would hold up the whole project. From that network you identify the critical path—the sequence of tasks that determines the project’s finish date—and you align start times, priorities, and resources accordingly. This makes coordination clearer and helps manage uncertainty across the schedule. Waterfall is a linear, phase-driven approach that emphasizes sequence and milestones, not specifically the probabilistic timing and networked planning that PERT uses. A harmonogram is simply a schedule diagram or plan, not a dedicated method for estimating and coordinating activities. Chaos engineering focuses on testing a system’s resilience by introducing failures, not on scheduling project work.
