Like many who have posted above me, I believe that there should be a more transparent relationship between managers and engineers in order for communication to be more clear and fluid. I also agree that a manager should have experience that is related to the project in order for there to be a good structure and a more successful outcome. This way not only can they ensure the project meets all the deadlines on time, but they can also provide any technical expertise that their engineers may lack. Also, having a manager from the same or similar field as the engineers would lead to more safe results and products as well as they are just as aware and concerned of all the possible dangers. They would be more hard pressed to make sure they are avoided rather than ignore warnings from their engineers, like in famous ethical cases such as the Ford Pinto case.
