Q1. Consider the following project activities:

Activity Name	Immediate Predecessor (list number/ name, separated by ,)	Normal Time
1		6
2		2
3	1	3
4	2	2
5	3	4
6	4	1
7	5,6	1
8	7	6
9	8	3

11	9,10	1

Fill the following table:

Activity Name	On Critical Path	Activity Time	Earliest Start	Earliest Finish	Latest Start	Latest Finish	Slack (LS-ES)
1		6
2		2
3		3
4		2
5		4
6		1
7		1
8		6
9		3
10		1
11		1
Project Completion Time =				Weeks
Number of Critical Path(s)=

Note : On critical path column the answer ( Yes or No ).

Q2.

Assume that ABC Company has invested a budget of 10 million riyals for XY project and planned to complete it in 10 months. Lets also assume that the company planned to spend the budget equally in each month. However, when the first two months has passed, the project manager has found out that the total of one million riyals spent. Suppose RP=0.25

Based on the above scenario, answer the following:

a) What is the cost variance, schedule variance, cost performance index (CPI), and schedule performance index (SPI) for the project?

b) How much will it actually cost the company to complete this project, and how long will it really take to complete it based on the performance to date?

c) What do you think of the project performance? over/under the budget? behind /ahead the schedule? Justify your answer.
