Critical chain and Path
A: The critical path method schedules early start and late start dates to planned activities, whereas the critical chain method schedules only late start dates to planned activities.
B: The critical chain method initially uses non-conservative estimates, whereas the critical path method is concerned with using more accurate estimates.
C: The critical path method focuses on managing the total float of network paths, whereas the critical chain method focuses on managing the buffer activity durations and the resources applied to planned schedule activities.
D: The critical chain method accounts for resource availability, whereas the critical path method does not.
My understanding is CPM doesn't consider resource limitation while CCM does. Is that right?
