Nandan Nilekani is cochairman of Infosys Technologies (nasdaq: INFY - news - people ), India's second-biggest outsourcing firm. Its success is the basis of his $750 million fortune. We caught up with Nilekani at the Infosys headquarters in Bangalore, where he talked about the company he helped build, the outsourcing industry and his first book, Imagining India: Ideas for the New Century (Penguin), just released.

FORBES ASIA: Will economic conditions change things for Indian outsourcing?

Nilekani: There will be deep ramifications. In the short term outsourcing will slow down. Companies will go slow on making decisions, the environment will be challenging. This is a big one, but even this cannot last forever. The U.S. has an enormous capacity for reinventing itself. That is clear from the fact that Barack Obama has been elected President.

As part of his campaign, Obama spoke against offshoring. Will this affect policy in the coming months?

Barack Obama will do things that are right for his country. He understands that outsourcing firms are partners in making American companies stronger, more efficient and successful.

India's outsourcing industry grew from a few billion dollars to $40 billion in the last few years. What do you see happen in the next five?

It is unlikely that we will see the growth rates of previous years. Not 30% to 40%.

After years of high growth, outsourcing companies have started layoffs. How will workers cope?

Many young people who joined the industry four or five years ago have only seen the good times. It was growth on steroids. They could have been lulled into a feeling that this is normalcy. We have to do a lot of things that are hard. The economic crisis is useful because it forces all of us to focus on productivity.

Infosys spends a huge amount of money and resources on training fresh hires. Is this a sustainable business model during these recessionary times?

We set up our leadership institute in 2001 and our training infrastructure in 2002 during a downturn. We think of our training as a long-term strategic advantage.

Talking about reinvention, have you reinvented yourself?

I used to take on a lot of things, thrash around, lose control and have nothing to report at the end of the day. My new motto is to be generous with my money but stingy with my time. My scarce capital is time, not money. I'm turning down meetings, invitations to speak. I have dropped all commitments on foreign company boards. I have decided that the place I want to spend time is India. Not to sound arrogant, but I use my name to improve my productivity. If I am going to the airport, then I will travel to three cities, ask people to make time for me, pack 15 meetings into three days and come back. Infosys has first call on my time.

Your idea on the flat world ended up inspiring a bestselling book authored by Thomas Friedman. What is the bestselling idea in your own book?

It is not one idea. A democratic country like India with a billion individualistic people cannot move in a particular direction based on one idea. It calls for a bottom-up change.

Does middle-class India live inside a bubble, having very little to do with the rest of India, which is very poor?

India's middle class has abdicated. In its extreme form, many Indians have left the country. But abdication is also living in gated communities, running our own generators, digging bore wells for our homes, sending our children to private schools--in my own case, sending them to college in the U.S. The middle class has never put pressure on the system. They have simply dropped out.

Does writing come easy to you?

I used my experience in writing software to write the book. When you write a software program that is large and complicated, just as this book is, then you structure it well, divide it into individual modules, write each module to be self-contained and make sure there are clear interfaces. I wrote a book that spanned 18 ideas. I sliced these into sections and put a wrapper around each.
