The latest problems with Boeing’s 737 MAX have reignited a debate among analysts and investors about who should run a global commercial aerospace company — an ace engineer or a professional manager. “To me, the [Boeing] problem is not the engineers, the problem is management,” says Vertical Research Partners analyst Rob Stallard. Of course, Boeing, and its chief rival Airbus need both. But the numbers appear to support Stallard’s point of view, that strong management is critical. Boeing had no immediate comment. Airbus didn’t respond to a request for comment. The issue is partly the nature of the aerospace business, which is characterized by heavy investment, high regulation, and product cycles measured in decades, making strategic choices as critical as engineering decisions. “This is the sort of business that, from a product perspective, you build on, or not, over a long period of time,” explains General Electric CEO Larry Culp.
