" it's that focussed leaders who will not compromise on quality or security and who have headed revolutionary products for decades create bad products compared to teams of management graduates who understand team-building because they went on a course about it once."
If you look at really big projects like CERN, or mainstream car builders, Boeing or Airbus, that's pretty much correct (except that European managers tend to be much,much better trained than Anglophone ones.) Then there's the armed forces, also highly trained in management and co-operation. Part of Eisenhower's genius was applying management techniques to invading Europe.
Every project tends to need a Type A person or three to kick it off and establish the outlines. But when it becomes an essential part of a lot of people's work, it needs the skilled administrators to keep the edifice functioning. The difficulty is usually for the founder to let go, while experiencing growing frustration because there are things outside his (or her, in some cases) control. One startup I worked for, the wife of the founder demanded he take a month off in the West Indies away from the phone. It probably saved his sanity.
Unfortunately there are always people like you about, willing to worship the Type As and validate their view of the world when you should be whispering in their ear "Remember, O Caesar, that thou art mortal".
