TRW Automotive is one of the world’s largest automotive suppliers,
producing braking, steering and suspension systems,
and occupant safety systems in nearly 200 locations on four
continents. After introducing Lean in manufacturing, the company
deployed Six Sigma in 2001, and applies the methodology
in both manufacturing and business processes. In general,

After considerable analysis comparing attitudes, practices and performance, the team identified a total of 52 improvement actions – 19 related to people, 10 to communication, nine to processes, eight to organizational structure, and six to leadership. For each category, a paired-choice matrix was used to prioritize the actions. The improvement actions included….Control
With TRW’s Six Sigma program still saving the company multiple millions of dollars annually eight years after the initial deployment, this project was not aimed at salvaging the program from disaster. Rather, it was a recognition of the need for the program to use its own continuous process improvement methods to continually improve itself…Click here to view a sample page of this project example>>>>
