What function group is the best decision maker for this scenario:$1.$ Ohmeda, a wholly owned company of the BOC Group, plans to grow the company's sales from $$95$ million in $1985$ to $$158$ million in five years by focusing on the sale of "high$-$tech" equipment. At the same time the company expects to sell Ohmeda's medical supplies business $($$$22$ million in sales$)$ and to transfer its medical gases business $($$$27\mathrm{.}2$ million in sales$)$ to another business unit of the BOC Group. The changes in Ohmeda's products combined with the planned growth in medical equipment cause the decision$-$maker to reassess the company's marketing system. The new thrust requires him to review the role of Ohmeda's direct sales and dealer sales coverage. In doing so$,$ the economics of three options are to be evaluated: a$)$ continuing with Ohmeda's present system, b$)$ eliminating dealer sales coverage, and specializing sales people by product group.
