Case 2: Highline Trading Services

Highline Trading Services provides three categories of service to its clients. Managing partner Freddie Mack is getting ready to prepare financial and personnel hiring (or layoff) plans for the coming year. He is a bit perplexed by the following printout he obtained, which seems to show oscillating demand for the three categories of services over the past eight quarters:

SERVICE

Year	Quarter	A	B	C
1	1	60	95	93
	2	45	85	90
	3	100	92	110
	4	75	65	90
Year	Quarter	A	B	C
2	1	72	85	102
	2	51	75	75
	3	112	85	110
	4	85	50	100

Examine the demand that this company has experienced for the three categories of service it offers over the preceding two years.

Assuming nothing changes in terms of advertising or promotion, and competition doesnt change, predict demand for the services the company offers for the next four quarters, and use Excel QM to confirm your results.
