Lean Six Sigma can generally be described as a combination of the Lean and Six Sigma methods. While the Lean method aims to reduce the lead time of a value chain, Lean Six Sigma focuses on reducing deviations and improving quality. Both methods therefore have their own focal points and together result in a comprehensive quality management and optimization concept that optimizes the process on the one hand and does not lose sight of quality on the other. Since companies are always striving to reduce their costs and at the same time increase their quality, flexibility and efficiency, Lean Six …
