Question

With respect to a CPM network, answer the following: (1) What are the activities in the network for which Earliest Start Time equals Latest Start Time? (2) Within a CPM network, can there be more than one critical path branch in the network? Why? (3) What would be the effect of scheduling all activities to start on their Latest Start date? (4) If you use the WBS items as activities, what additional information is required before you can construct a CPM network? (5) Which of the following items is not included in the calculations for a CPM network? Earliest Start, Critical Path, Manpower Loading, Project Finish Date.

Explanation / Answer

(1) What are the activities in the network for which Earliest Start Time equals Latest Start Time?

Ans: As per CPM network For all activities that are in the critical path, the earliest start time will be the same as latest start time and also the earliest finish time will be the same as latest finish time.

(2) Within a CPM network, can there be more than one critical path branch in the network? Why?

Critical path is the longest duration path through the entire CPM network. In large networks, there may be multiple critical paths, this situation happpens when some critical activities are grouped in more than one sequence. And then those multiple paths take the same time to complete.

(3) What would be the effect of scheduling all activities to start on their Latest Start date?

Sometimes things take longer time than planned. Starting all activities on the latest possible start date causes all the slack out of schedule. If we schedule all activities to start on their Latest Start date then glitch will stall and it will become late.So it is not a good thing.

(4) If you use the WBS items as activities, what additional information is required before you can construct a CPM network?

If we use work breakdown structure(WBS),we need to identify each task that is involved in the project which includes higher-level activities. The main thing is that work breakdown structure breaks down projects into several sections. Hence first we need to identify the main deliverables and then you can start breaking down them into smaller chunks.

(5) Which of the following items is not included in the calculations for a CPM network? Earliest Start, Critical Path, Manpower Loading, Project Finish Date.

Manpower Loading
