In addition to using engineering prototypes during the product integration phase of product development, Cummins and other companies we visited used other prototypes-such as production representative prototypes-in the remaining product development phases before production, as shown in table 4, to demonstrate product reliability and process control.
Cummins saved a lot in production money by using engineering prototypes.
