Text: Commercial companies demand knowledge from virtual or engineering prototypes, 90 percent of required engineering drawings for the product supported by test results, demonstration that the product meets customer requirements, a series of disciplined design reviews, and stakeholder agreement that the design is stable and ready for product demonstration before a commitment is made to move forward and invest in product demonstration.
Entailment: The knowledge provided by virtual prototypes is demanded by commercial companies.
Contradiction: The knowledge provided by engineering prototypes is simply not demanded by commercial companies.
