Which Indian companies are using six sigma?

There are several companies who are engaged in Six Sigma one way or other. Most of the Indian operations of MNCs like GE/Motorola/Allied Signal etc have Six Sigma built into their systems and even though some Indian Managers(!) like to avoid, they can not!

The most significant program undertaken by an Indian company is by Wipro so far. Perhaps thanks to Azim Premji ( Azim Premji is a close friend of Jack Welch and heavily influenced by GE ‘s way of doing business).

TATAs including TISCO/TELCO and Taj Hotels have a robust Quality Program of their own and surprisingly similar to 6sigma.

ASIAN PAINTS, WHIRLPOOL, LG, L&T SWITCHGEAR, RELIANCE PATALGANGA, TVS SUZUKI, VIP INDUSTRIES, PIDILITE INDUSTRIES ARE ALSO ALL DOING SIX SIGMA.
