The Logistics Savings: Bulk delivery was cheaper than drum delivery for the supplier. Customers could save 5 cents a pound in-grease purchase costs, and eliminate wastage, drum handling, and disposal costs. Market Resistance: Customer adoption was so slow that three years after introduction, the specially designed bulk grease delivery truck still was underutilized. The Causes: The logistically better system failed due to poor sales training by the grease supplier. On the buying side, engineering resistance to an unfamiliar idea by customers' misconceptions about the relatively small costs departments, of adaptation to the new system, and fear of being tied to one supplier kept customers from switching over.
