If you are working as a consultant, can you please share your experience. Main doubts.

1. As a consultant, do you have the power to decide what is good solution for a particular problem?
2. Does MBA help > 15% to become a consultant or is just relatively good understanding of technology and the business enough? (Is the MBA needed)

I think very few here would be IT Conusltants (people who would decide what is the best set of application for the next new bank - ABC India bank), so request other consultants to help.
