Controlling is one of the toughest problems faced by the Wheeled Coach. Operating according to the strategy of mass customization and responsiveness, management knows that success is dependent on tight inventory control. Anything else results in an inability to deliver promptly, chaos on the assembly line, and huge inventory investment. Wheeled Coach
finds that almost 50% of the $40,000 to $100,000 cost of every ambulance in manufactures is purchased materials. A large proportion of that 50% is in chassis (purchased from Ford),
aluminum (from Reynolds Metals), and plywood used for flooring and cabinetry construction (from local suppliers). Wheeled Coach tracks these A inventory items quiet
carefully, maintaining tight security/control and ordering carefully so as to maximize quantity discounts while minimizing on-hand stock. Because of long lead times and scheduling need at Reynolds, aluminum must actually be ordered as much as 8 months in advance. in a crowded ambulance industry in which it is the only giant, its 45% of competitors don’t have the purchasing power to draw the same discounts as Wheeled Coach. But this competitive
cost advantage cannot be taken lightly, according to president Bob Collins. “Cycle counting in our stockrooms is critical. No part can leave the stockrooms without appearing on the bill
of materials.”
Accurate Bills of Materials are the requirement if productions are going to be built on time. Additionally, because of the custom nature of each vehicle, most orders are won only after a
bidding process. Accurate BOMs are critical to cost estimation and the resulting bid. For these reasons, Collins was emphatic that Wheeled Coach maintains outstanding inventory
control.
