A Six Sigma project was launched at 3M Brazil in 2002 to reduce losses in the production of electrical tapes. The project used the DMAIC methodology over five phases: Define identified problems and objectives; Measure identified 239 variables and selected 58 critical ones using cause-effect matrices and process maps; Analyze further studied the 58 variables and identified 8 then 3 key ones using Multi Vari and FMEA tools; Improve developed experiments on the 8 variables to improve them; Control developed a process monitoring system. The project achieved its 17.9% loss reduction goal and exceeded its 30% unit price reduction target, gaining 31%.
