Well, it is difficult to find an industry with worse track record of product quality and reliability than the software industry, I wouldn't use software development management as reference. (also two decades is software development... and software usage!!) In my experience managers lacking domain knowledge make more harm than good but are excellent putting emphasis on adjacent and auxiliary parts they are good at. Anyone put in charge of something they are not competent in would do the same.
