Efficiency and Effectiveness...
My dream was to study at the IIM, Ahmedabad. But that could not happen due to various reasons.
In the early eighties, while I was in business, I wished to pursue management education at the newly started LIBA (Loyola Institute of Business Administration).
After passing the entrance examination I was interviewed by three persons, one of them, Prof. Jay Amaran (who later married my aunt's grand-daughter).
I was bombarded with questions, more to know how I answered (perhaps). They were not all keen to give me admission since they opined that I was an entreprenuer. Seats were few.
In those days Peter Drucker was my role model.
One of the questions in the interview: What is the difference between efficiency and effectiveness?
Pat came my reply: One does things right and the other does the right things. (Courtesy: Peter Drucker!!)
The interview was interesting to both parties, but the admission was denied!!
