Comparison of Three Commonly Adopted Improvement Methodologies See reference, How To Compare Six Sigma, Lean and the Theory of Constraints Comparing the main points of the three improvement methodologies: Six Sigma, Lean Thinking, and Theory of Constraints Six Sigma Approach Define, measure, analyze, improve, control (DMAIC) cycle Six Sigma Tools Tools common to other quality programs are used in Six Sigma Failure mode and effects analysis (FMEA) Structured approach to identify, estimate, prioritize, and evaluate risk of possible failure at each stage of a process Risk priority number (RPN) is calculated and is based on Extent of damage resulting from failure (severity) Probability failure takes place (occurrence) Probability of detecting the failure (detection) High RPN items are designated for improvement first Example Design of experiments (DOE) Statistical approach used for determining the cause-and-effect relationship between process variables and an output variable Approach allows for experimentation with many variables simultaneously Six Sigma Quality To achieve a Six Sigma quality (according to the assumptions
