Question to a Project Management Professional

Question Select the best option
Honestly speaking, many project managers don’t see the difference between the critical path method and the chain method. What would be the best definition of the difference between the two?
  1. The critical chain method does not consider the effects of resource allocation, resource optimization, and resource leveling on project duration.
  2. The critical chain approach is a descendant of the critical path method.
  3. The critical chain method introduces the concept of buffer management, while the critical path uses float management.
  4. Practically, there is no difference. The two names are often used interchangeably.
Answer & Explanation
Right answer
  1. The critical chain method does not consider the effects of resource allocation, resource optimization, and resource leveling on project duration.
  2. The critical chain approach is a descendant of the critical path method.
  3. The critical chain method introduces the concept of buffer management, while the critical path uses float management.
  4. Practically, there is no difference. The two names are often used interchangeably.

Explanation : The critical chain method focused on managing the buffers instead of managing the total float of network paths, as the critical path method does. It is indeed developed from the critical path method, but this not answer the question.
