What is the best approach to build a framework for uncommon cases?
For example I was given the following case: A Government in one of the state in India wants all people to change from using standard bulbs lights to LED bulbs. They decided to subsidize the LED bulbs. They ask Mckinsey to help them finding the right subsidizing amount.
The moving to LED the government's objectives is to achieve budget savings and ecology friendly state.
Looking forward to seeing your suggestions.
