Understanding Learning Curves
Jenny Wilson is a buyer at Flextron, a manufacturer of large industrial pumps. She has a requirement for a customized subassembly that a preferred supplier, Vistral, is building for the first time. She is preparing for negotiation with Vistral, where a key issue will be the price of the subassembly. Given the unique nature of this subassembly, Jenny expects to incorporate into the contract price reduction targets based on learning curve estimates. While Jenny does not have specific data for Vistral, she has accumulated data for a subassembly that was similar in design and manufacturing complexity.
