Lean Six Sigma: Yellow Belt, Green Belt, Black Belt
Lean Six Sigma (LSS) is a data-driven process that uses statistics, the DMAIC method, graphs and other tools to provide a framework for breakthrough performance improvement. The central idea behind LSS is that if an organization can measure how many “defects” there can be in a process, then it can easily and systematically identify ways to eliminate them with the aim of reaching as close to zero defects as possible.
