1)The critical path for a project with uncertain activity times is not known for certain until after the project is completed.

   

 

2. A project may be defined as a set of complex interrelated tasks with different requirements regarding activity time and resources, but with a high degree of repetitiveness.

   

 

3. Gantt charts fail to indicate the interdependence among project activities.

   

 

4. The critical path refers to the sequence of activities that represent the longest time path through a project network.

   
 

5. The term total slack refers to the amount of time an activity can be delayed without delaying the start of a subsequent activity.

   

 

6. It is possible to delay the start of a non-critical activity and, in the process, make a following activity critical.

   

 

7. Total slack for an activity may be shared with following activities.

   

 

8. The term Late Finish refers to the latest time an activity may begin without delaying the completion of the project.

   

 

9. A major flaw in critical path analysis with uncertain activity times is the conservative nature of the expected project completion time.

   

 

10. Before calculating a Late Start time for an activity, the Late Finish time must be known.

   

 

11. The single important attribute of a project manager is leadership ability.

   

 

12. Schedule variance is the difference between budgeted cost for work performed and actual cost of work performed.

   

 

13. The term calendar is used in project management to keep track of the days and hours required for completion of projects.

   

 

14. Time variance is calculated by subtracting actual time used for work performed from scheduled time for work performed.

   

 

15. When delays occur owing to technical difficulties, performance becomes the source of unexpected project management problems.

   
 

16. Developing a project network is the only major concern for implementing critical path analysis.

   

 

17. Merge node bias occurs where the project network contains non-critical paths with small total slack times.

   

 

18. Estimates of project expected completion time and variance are usually not biased when based on the single critical path.

   

 

19. When crashing activities for construction projects the contractor's minimum cost duration may not coincide with the client's target completion date.

   

 

20. A major assumption in project network analysis is that sufficient resources are available to perform many activities concurrently.

   

 
 

21. Which of the following is not  about a critical path in a project network with certain activity times?

   

 

22. For a project with uncertain activity times, the probability of project completion exceeding the expected time calculated for the critical path is:

   

 

23. A key assumption underlying project networks is:

   

 

24. The Beta distribution is useful in network analysis because it:

   

 

25. A major weakness with project completion time analysis with uncertain activity times is the:

   

 

26. Monte Carlo simulation of project networks is not recommended when:

   

 

27. Gantt project charts are useful for all but one of the following reasons:

   

 

28. Which one of the following is not an objective of activity crashing?

   

 

29. A resource-leveled schedule has all but one of the following characteristics:

   

 

30. Implementing critical path analysis is faced with all but one of the following problems:

   

 

 

31. Which one of the following attributes is not considered in the selection of a project manager?

   

 

32. The four sequential stages of team development include all but one of the following:

   

 

33. Which one of the following is not considered a source of unexpected project management problems?

   

 

34. Projects are terminated for all but one of the following reasons:

   

 

35. A project history report should include all but one of the following items:

   

 

36. Which one of the following is not considered a source of variance on the earned value chart?

   

 

37. Which one of the following makes performance a source of unexpected project management problem?

   

 

38. Which one of the following is not a critical time estimate for a Beta distribution?

   

 

39. Which one of the following allows the manager to make probability statements with regard to meeting project objectives?

   

 

40. The amount of time an activity can be delayed without delaying the completion of the project is referred to as:
