Take the following as truth: 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.
Then the following statement: "Engineering prototypes are preferred over virtual prototypes by commercial companies." is true, false, or inconclusive?
Answer: Inconclusive
