27. Consider a project with six activities: G, B, C, D, E, and F. Assume G and F can be started as soon as the project is kicked off. B can start as soon as G is completed, C can start as soon as both G and F are completed. D will start as soon as both B and C are completed. E will start as soon as D finishes. Which of the following choices is the correct collection of immediate precedence relationships in the project network?     G--> B, F--> C, B --> D, C--> E, D--> E, F--> D     G--> B, G--> C, B --> D, C--> D, D--> E, F--> C     G--> B, G--> C, B --> D, C--> D, D--> E, D--> F     None of choices     G--> B, F--> C, B --> D, C--> D, D--> E, F--> D     G--> B, G--> C, B --> D, C--> D, D--> E, D--> F

Consider a project with four activities. Activities A1, A2, and A3 all can start immediately.However, A4 requires the completion of A1, A2, and A3. A1 can take any time between4 and 8 days. A2 can take any time between 2 and 6 days. A3 always takes 5 days. Inaddition to A4, which activity (or activities) has the potential to be on the critical path?a. A1b. A1 and A2c. A2 and A3d. A1, A2, and A3e. None of these options is correct

50 The phases of project management are:  Select one: a. different for manufacturing projects than for services projects  b. GANTT, CPM, and PERT c. planning, organizing, staffing, leading and controlling  d. planning, programing, and budgeting  e. planning, scheduling, and controlling

To help with preparations, a couple has devised a project network to describe the activities that must be completed by their wedding date. A project network with 10 activities and 13 directed arcs is shown. Activity Start is connected to activity A and to activity B. Activity A is connected to activity C and to activity D. Activity B is connected to activity E. Activity C is connected to activity H. Activity D is connected to activity F and to activity G. Activity E is connected to activity F and to activity G. Activity F is connected to activity H. Activity G is connected to activity Finish. Activity H is connected to activity Finish. Activity Finish has no arcs directed to other activities. The following table lists the activity time estimates (in weeks) for each activity. Activity Optimistic Most Probable Pessimistic A 4 5 6 B 2.5 3 3.5 C 5 6 7 D 5 5.5 9 E 5 7 9 F 2 3 4 G 9 11 13 H 7 8 15 Based only on the critical path, what is the estimated probability…

12. In general, work packages should not exceed 10 work days. 13. The project structure chosen to manage the project will have little impact on the actual project work to be accomplished. 14. An activity is an element of the project that always requires time but may or may not require resources. 15. The forward pass through a project network determines the critical path. 16. Different activities along the same path can have different total slack. 17. It is possible to have more than one critical path at the same time. 18. Free slack applies to an entire project network. 19. Lags are used to break larger activities into smaller segments so that activities that follow can be started earlier. 20. In a balanced matrix form of project management, the project manager is responsible for defining what needs to be accomplished while the functional managers are concerned with how it will be accomplished.

There are four critical paths in a network. A-B-C-D-E, A-F-G-E, A-H-J-K-L-E and A-S-T-E. Each activity in this network can be crashed by 100 hours. The maximum possible reduction in the project duration will be: a. Insufficient information b. 1300 hours c. 500 hours d. 400 hours e. 600 hour

A simple CPM network has three activities, N, O, and P. N is an immediate predecessor of O and of P. O is an immediate predecessor of P. The activity durations are N = 9, 0 = 7, P = 5. O A. The critical path is N-O-P, duration 21. O B. The network has no critical path. O C. The critical path is O-P, duration 12. D. The critical path is N-P, duration 14. O E. The critical path is N-O-P, duration 7.
