Critical Path Order

Question

A project has activities on the critical path that must be completed before other activities can start.

Task A is dependent on Task C before Task D can be completed.

Task A requires task B to start.

Task B takes twice as long to complete as Task C.

Which of the following is the appropriate ordering of the critical path?

A. B. C. D.

D.

The critical path is the sequence of activities that determines the duration of the project. The activities on the critical path must be completed on time, or the project will be delayed.

Let's analyze the tasks in the given scenario:

  • Task A is dependent on Task C before Task D can be completed. This means that Task C must be completed before Task A can start, and Task A must be completed before Task D can start.
  • Task A requires task B to start. This means that Task B must be completed before Task A can start.
  • Task B takes twice as long to complete as Task C. This means that Task B will take longer than Task C to complete.

Based on this information, we can determine the appropriate ordering of the critical path:

  • Task C must be completed before Task A can start, so Task C is the first activity on the critical path.
  • Task B must be completed before Task A can start, so Task B is the second activity on the critical path.
  • Task A must be completed before Task D can start, so Task A is the third activity on the critical path.
  • Finally, Task D can start after Task A is completed, so Task D is the last activity on the critical path.

Therefore, the appropriate ordering of the critical path is option D: B, C, A, D.
