Duration (weeks) 2 Immediate Predecessors 5 Activity Description A Write Instructions B. Select Operators C. Train Operators D. Announce new service E. Purchase, ship, and receive equipment F. Test new operators on equipment 4 A, B B 5 6 2 CE a) (5 points) Using Critical Path Method, find earliest start time, earliest finish time, latest start time, and latest finish time for each of the activities. What is the earliest completion time for this project? Identify critical activities and paths. What is the maximum delay time for each activity such that it will not increase the project completion time? b) (5 points) After examining his initial list of activities, Dr. Windsor realizes that while preliminary parts of operator's training can take place before the new equipment arrives, the last three weeks of training must take place only after the equipment arrives. Re-do the project plan, completion time estimate, and critical activity identification using CPM and taking this new information into account. c) (5 points) Now suppose activities A and B both have to be done using same resources. This just means that activities A and B cannot be completed at the same time anymore and should be completed sequentially. Re-do the project plan, completion time estimate, and critical activity identification using CPM and taking this new information into account. (Note: the information in part b is still to be considered)
