Using Lean Six Sigma to reduce scrap, re-work and costs

Tenneco manufactures clean air and ride performance products for cars, trucks, and commercial and agricultural vehicles for customers in more than 100 countries.

“Our manufacturing facilities produce high-quality products and systems using state-of-the-art manufacturing processes and advanced optimisation tools,” said Dan Wolfe, Lean Six Sigma master black belt and master black belt manager for North America at Tenneco. “Tenneco employs Six Sigma and Lean extensively to assure consistent levels of quality for our customers and to improve effi ciency across all of our facilities.”

As part of a Six Sigma initiative to reduce scrap and rework, a team at the company’s Litchfield, Michigan, facility used Minitab Statistical Software to assess and optimise its processes for manufacturing steel tubing for vehicle exhaust systems.
