Question 1: (17 marks)

The data given in Table 1 shows PV, EV, and AC values in thousands of dollars for the first 30 weeks of a projects execution before its completion. Answer the following questions:

a. Using three different pen colors, draw a graph showing the curves PV, EV, and AC. Label appropriately the curves and the x-axis and y-axis (5 marks);

b. Indicate the intervals of time where the project is on schedule, going faster or slower than the planned schedule (4 marks);

c. Indicate the intervals of time where the project is on budget, under or over the planned budget (4 marks);

d. Evaluate the budget gain or loss that occurred on week 15 in dollars (2 marks);

e. Evaluate the schedule status on week 25 (2 marks).

Activity ID	Week Number	PV $(000)	EV $(000)	AC $(000)
A	5	7	5	2
B	10	13	10	7
C	15	18	15	12
D	20	20	20	20
E	25	22	25	28

   F	2	D, E

Question 4: (11 marks)

What is the Work Breakdown Structure (WBS)? Who is responsible for creating it? And what is its purpose? (5 marks).

Provide an example of WBS for a project of your own. The example should include the following:

• A project title; (1.5 marks)
• Outlined relevant phases; (1.5 marks)
• Activities are to be named and numbered appropriately; (1.5 marks)
• Activities are to be joined appropriately and logically. (1.5 marks)
