We will never have an innovative culture unless you accept failure. Nine out of 10 products fail. Most new ideas are bad ideas. So you need to have the capacity to tolerating many bad ideas in the hope of a good one.

We need to find ways to solve problems in a systematic and repeatable way, and not come up with a particular solution to each problem. It is to say, instead of the Nano why didn't we come with a bullock cart with a fuel pump or an engine? Also we need to have a non-linear model which will not depend on revenue growth, highly positively correlated with people growth.
