With respect, its not necessary to be "QUALIFIED" to be a manager from "BUSINESS SCHOOLS" to be a good manager. Its quality that develops over a period of time which can be inherent from school days too. For instance Dhirubai Ambani never went to a BUSINESS SCHOOL to get qualified as manager, and world knows about his managing skills & ability. Many more like him are out there.
So its basically a inherent quality, which only gets polished / fine tuned thru formal education.
