Text: A commercial company considers engineering drawings4 to be a good measure of the demonstrated stability of the product's design because they represent the language used by engineers to communicate to the manufacturers the details of a new product design-what it looks like, how its components interface, how it functions, how to build it, and what critical materials and processes are required to fabricate and test it.
Entailment: Engineering drawings are regarded as a good indicator of product design stability.
Contradiction: Commercial companies see no merit in engineering drawings.
