What are the main causes of outsourcing in India?

Outsourcing to India is more about getting high quality work similar to  what is done in US at a  lower cost in India.

A service which costs around $48 per seat per hour in the US is accomplished at $11-12 per seat per hour in India. So, US companies save almost 75 per cent by outsourcing their activities to India.

My  Dear Ria,

                              Thank you for the valuable comments.

With the advent of globalization, more and more jobs are being outsourced to India. The outsourcing trend has brought with it a vast number of opportunities to India.
Outsourcing to India is now more about high quality rather than cost. Indian companies are fast scaling up to match or surpass international quality standards and are ensuring that they stay ahead through stable quality systems and continuous quality improvement.
