Premise: A Cummins representative stated that not using prototypes becomes a matter of pay me now or pay me later, meaning that it is far less costly to demonstrate a product's design early in development with prototypes, concepts, and analyses than to incur the cost of significant design changes after a product has entered production-a much more costly environment to make changes.

Hypothesis: A forum on product design was held where someone from Cummins spoke. 
Relation: neutral
