[All PMI-SP Questions]

Terri is the project manager for her organization and she is working with her project team to develop the project schedule. She has identified the float in her project although some of the activities where float exists may be susceptible to risk in the project execution. She is also concerned that the critical path may change during the project if the risk events come into execution. What scheduling method is Terri using in this example?

  • A. Critical chain method
  • B. Risk analysis method
  • C. Activity on the arrow method
  • D. Critical path method

Suggested Answer: D 🗳️
Terri is using the critical path method in this example. The question acknowledges that Terri has identified float and the critical path, but it makes no mention of the availability of project resources - something the critical chain method focuses on. Critical Path Method, abbreviated CPM, or Critical Path Analysis, is a mathematically based algorithm for scheduling a set of project activities. It is an important tool for effective project management. It provides the following benefits:
Provides the graphical view of the project. Predicts the time required to complete the project. Shows which activities are critical to maintain the schedule and which are not. CPM models the activities and events of a project as a network. Activities are depicted as nodes on the network, and events that signify the beginning or ending of activities are depicted as arcs or lines between the nodes.
Incorrect Answers:
A: The question does not indicate that Terri is concerned with the availability of project resources - as she would be if she were using the critical chain method.
B: The risk analysis method is not a valid scheduling technique.
C: Activity on the arrow method is not being described in this question.
