6. What is 'Consumer orientation'? Explain the important stages of developing suitable marketing process for:
i) manufactured products and ii) services.

7. A project consisting of 12 distinct activities is to be analysed by using PERT. Draw the PERT network. Indicate the expected total slack for each activity and hence indicate the average critical path. With in how many days would you expect the project to be completed with 99% chances?

ACTIVITY	PREDECESSOR ACTIVITY	OPTIMISTIC TIME (Days)	NORMAL TIME (Days)	PESSIMISTIC TIME (Days)
A	-	2	2	2
	B			-
		1	3	7
C	A	4	7	8
D	A	3	5	7
E	B	2	6	9
F	B	5	9	11
G	C,D	3	6	8
H	E	2	6	9
I	C,D	3	5	8
J	G,H	1	3	4
K	F	4	8	11

8. The following table gives the information about various activities of a project network.

Activity	Normal duration (Days)	Normal Cost (Rs.)	Crash duration (Days)	Crash Cost (Rs.)
1-2	9	8000	7	10,000
1-3	5	5000	3	8,000
2-3	7	7000	5	8,600
2-3	8	6000	6	7,000
3-4	6	9000	4	11,400

The overhead costs are Rs 1300 per day. Determinant the optimum cost and duration of the project.
