Question A

A project is made of 7 activities:

Activity	Initiation	Analysis	Data Modeling	Process Modeling	Design	Feasibility Analysis	Documentation
a	14	14	3	1	2	4	5
b	18	34	11	1	4	12	15
m	16	15	4	1	3	5	13
Predecessors	--	--	Analysis	Analysis	Data and Process Modeling	Data and Process Modeling	Initiation and Analysis

1. Draw an A on A chart.
2. Find the critical path and the project duration.

Question B

A project is made of 8 activities:

Activity	A1	A2	A3	A4	A5	A6	A7	A8
Duration	20	13	15	9	20	30	20	25
Pre. Activity	-	-	-	A2	A1,A3,A4	A1,A3,A4	A5,A6	A6

1. Draw an A on A chart.
2. What is the critical path? What is the project duration?
3. When the latest can we start activity A1?
4. When the latest can we start activity A5?
5. Refer to the critical path you found in b. Assume that every activity is normally distributed. Each activity's mean is given in the table above. Each activity's standard deviation is 20% of its mean (for example, the mean duration of activity A2 is 13 and its standard deviation is 2.6). What is the probability that the project will last more than 80 days?

Question C

Complete the following table:

slack	LF	LS	EF	ES	Predecessor(s)	Duration	Task
					-	5	A
					-	10	B
					A	20	C
					A,B	13	D
					C,D	10	E
					A,B	25	F
					E,F	8	G
