Using the CPM approach to Project Management, what is the critical path and completion time for the for following network diagram?

ACTIVITY	Precedent Activity	Completion Time (days)
A	NONE	1
B	A	2
C	B	4
D	C	3
E	C	5
F	D	3
G	F	3
H	G, E	2
I	H	1

		A-B-C-D-F-G-H-I = 19 days
		A-B-C-E-H-1 = 15 days
		A-B-C-D-E-F-G-H-I = 24 days
