A.Create a network diagram for the project below. What is the critical path and duration? (Hint your diagram should have the three paths listed in the responses below, and your path completion times should be identical to those in the respones below)

Activity	Duration	Predecessor(s)
A	2	---
B	5	---
C	3	---
D	2	A
F	3	D
E	3	C
G	4	B, E
J	3	G

		BGJ 12
		CEGJ 13
		ADF 7
		All of the paths are critica

b.Which activities in the project need to be completed for the project to be complete?

		BGJ 12
		CEGJ 13
		ADF 7
		All of them

c.Activites ________ have ______ days of slack

		A, D & F, 6
		B 3
		C, E, G & J 13
		A & B 2

d.The latest start and latest finish dates for activity D are

		2, 4
		8, 10
		10, 13
		2, 8

e.What happens if activity F actually takes 7 days instead of 3?

		The project completion will be delayed 4 days
		The project completion will be delayed 7 days
		The project completion will not be affected
		The critical path shifs to ADF

f.Before the project, we receive revised estimates of 6 for activity A and 5 for activity D. What effect does this have?

		The project completion will be delayed 11 days
		The project completion will be delayed 6 days
		The project completion will not be affected
		The critical path shifs to ADF and the project completion estimate increases to 14 days

g.In order to buffer our project against uncertainty in activity completion times (the possibility that an activity time will exceed its estimate), we should place a feeder buffer ___ and a project buffer.

		Before F, before J
		Before E, after F & J
		Before G, after F & J
		After F, before J
