1. 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	1
   C	B	2
   D	C	3
   E	D	4
   F	E	5
   G	E	4
   H	F, G	1

   		A-B-C-D-E-F-H = 17 days
   		A-B-C-D-E-G-H = 16 days
   		A-B-C-D-E-F-G-H = 22 days
   		A-B-C-D-E-F-H = 19 days
   		A-B-C-D-E-G-H = 19 days
