I was some what convinced with the author, Nalin garg, /but the author has forgotten one thing that with the experience that three rules can be managed, you cannot blame a b school for it as the markets are changing at fast pace and the thing which is good in one region cannot be implemented on another, and to know the market condition with proper scenario they must go to the base of the market and be part of the frontline force to understand it , As the situation in the higher up is different from field. The intiative and risk taking, adaptibility and application is matter of experience.
