Cummins Inc. (NYSE: CMI) and Eli Lilly and Co., two of Indiana’s largest corporations, are joining forces to help minority-owned businesses at Indiana Black Expo’s Summer Celebration.

The two companies are sponsoring a workshop July 15 on Six Sigma, the business problem-solving technique credited with saving corporations millions of dollars annually, as part of the Black Business Conference at the 38th annual event in Indianapolis.

 “Lilly has successfully used Six Sigma for more than three years,” said Liz Klimes, Vice President of Six Sigma for the pharmaceuticalny. “We’re pleased to have an opportunity to share our expertise and experience with local businesses.”

“Companies that undertake this training will see increased opportunities not only as a supplier to Cummins but as a supplier to any number of other leading corporations,” said Gordon F. Fykes, Director of Diversity Procurement for Cummins, which produces diesel engines and related technology as well as power generation systems.
