Question 1 (10 points):

Mark the following statements as either TRUE (T) or FALSE (F):

1. Because of its flexibility, project management is equally useful in ongoing, routine

work as well as unique, one-time projects.

2. A program is a task within a project.

3. One of the major disadvantages of the project form of project management structure is that it tends to be more expensive than other forms of organizing.

4. A project manager must be flexible and creative and have the ability to adjust rapidly to changes.

5. The Pay Back method of project selection takes into consideration the time value of money.

6. Responsibility matrices are used primarily with small and medium sized projects and have limited use in large projects.

7. Once management has committed to a project, it is not possible for them to change the funding allocated to the project, or to change the deadline of the project.

8. In developing a project network, each activity should have a unique identification number that is smaller than the identification numbers of activities that follow it.

9. Resource leveling is only used on projects which are resource-constrained.

10. The risk is highest in the earliest phases of the project life cycle.


Question 2 (15 points): You work for a company which expects to earn at least 18 % on its investments. You

have to choose between two similar projects. Your analysts predict that inflation rate will be a stable 3 % over the next 7 years. Below is the cash flow information for each project. Which of the two projects would you fund if the decision is based only on financial information? Why?

Question 3 (25 points): Given the project information summarized in the following table:

Activity Predecessor Activity Duration (days)

A - 2 B A 7 C A 10 D A 4 E B 6 F B, C 5 G C, D 8 H D 9 I F, G 12 J F 5 K E, J 5 L G, H 6 M F, H 4 N I, K, L, M 3

Using the following legend to represent the nodes:

1. Draw the Activity on Node (AoN) network. 2. Calculate the early start (ES), early finish (EF), late start (LS), late finish (LF) and

slack. 3. Find the critical path (CP). 4. Discuss the impact on the activities if the project target completion time was set to 30

days.
