Companies run by engineer/production type CEO's, it seems to me, do better than by "number crunching" CEO's.
You gotta have accountants, comptrollers, money managers for a company to survive, obviously. To me, it's the emphasis on production, if there's a passion for the product or if the product is but a commodity to feather the bottem line.
Bill Ruger is an example. He built guns that interested him, often against "conventional wisdom". It was his conviction (passion) that a single shot rifle would sell. He had to lead and lead he did. The rest, as they say, is history.
Bill Ruger never "led from behind", a concept taking hold in Washington D.C....
