Lean and Six Sigma: Integrating Lean and Six Sigma in aSystematic Approach

摘要

Lean Manufacturing and Six Sigma are both powerful tools to improving quality, productivity, profitability andrnmarket competitiveness. Six Sigma is focused on reducing variation using a problem solving approach andrnstatistical tools. Lean Manufacturing focuses on eliminating waste and improving flow using various Leanrnprinciples and their respective approaches. As stand alone tools, companies can achieve strong improvements.rnUsing either tool alone has its limitations. However, by combining the Six Sigma DMAIC methodology with leanrnmanufacturing tools, companies have a more appropriate toolkit to address all types of process problems and canrnreap even more dramatic gains. An integrated approach to process improvement is presented using Leanrnmanufacturing principles and Six Sigma. The approach begins with Value Stream Mapping to identify gapsrnbetween the current and future state. Six Sigma is then used to ensure an improvement roadmap with a problemrnsolving approach. Lean manufacturing techniques are used in conjunction for process improvement.
