In an Advanced Manufacturing Engineering a Senior Engineer spends two years in a particular job. He would spend the first year in Design Engineering, learning the overall system for a very complex piece of office equipment. This product was in the final stage of development. The production start-up is at the end of the year. The engineer would be spending the second year on the manufacturing floor solving performance problems. The manufacturing had experienced great difficulty determining the cause of the final test failures in the past. A basic performance assumption that was explained to him bothered him during his training. When he challenged it, he was told in no uncertain terms that particular challenge was outside the scope of his responsibilities, that he was wrong, and that he should just accept it as a known fact. Should he drop the question? Should he go ahead with his idea of determining the cause of test failures. (In either case, support your answer with suitable assumptions and justifications)
