For turbocharger blades at Concorde, scrap stemming from miscutting during the cut-off operation was identified as being Critical to Quality. A team was put together to focus on the project the goal for which was to reduce miscut scrap by 90 percent. During the process, the team went through the Measure, Analyze, Improve, and Control Steps that characterize the Six Sigma- approach.
