As the 21st century approached, the leaders of Cummins Inc. set about to reshape the Fortune 250 company into one that was less cyclical, more diversified, more results-oriented and committed to turning a greater share of its sales into profits. They wanted to expand the Indiana-based enterprise into a global power while retaining the bedrock values that were so much a part of Cummins' history. They sought a cultural upheaval that would create a "New Cummins." In doing so, they would grapple with the most critical economic reversals in the company's history, institute Six Sigma as an ongoing improvement method, recast Cummins' brand identity, cultivate significant global growth and technological advancement, and increase the company's market capitalization tenfold. This is the story of the remarkable transformation of Cummins--and of the men and women who made it possible.
