Both the Lean and the Six Sigma methodologies have proven that it is possible to achieve important improvements in cost, quality, and time by focusing on process development and performance.
Lean will add another dimension of improvement in process speed and reduction of non-value add cost, then, by accelerating process speed, Lean provides faster feedback and more cycles of learning enhancing the power of Six Sigma tools. The Six Sigma tools will focus more on quality improvement rather than time management.
