Blending the Methodologies: Making Six Sigma "Leaner" That puts the onus for deciding the methodology into one place, and ensures that all candidate projects are evaluated for their potential gains. The company could, however, consolidate the decision-making process into one department. The department manager might propose a project to one group or the other, based on that manager's understanding of which is more suitable. If the company has separate "centres of excellence" for Six Sigma and Lean practitioners, projects might be selected separately also. It may already be obvious that a process has significant waste, or that a "finished goods" warehouse is bulging with inventory. ![]() Other projects could fit better with Lean techniques. The article, " Choose a Six Sigma Project", shows how to compare projects in order to determine which is the best match for the Six Sigma methodology. ![]() "Simply"…and that is a loaded word…use the approach most suited to the problem at hand. The most obvious approach is to avoid blending these methodologies. Also, the "Lean" project gives more autonomy to workers, at least to make suggestions for improvements. A "Lean" project seems to assume the analysis is complete, since it does not explain how to minimize or maximize. Build "continuous improvement" into every process, by bringing suppliers and front-line workers "into the loop"īased on the above simplified lists, a Six Sigma project would concentrate on analysis and finish by implementing rigid controls.Produce what the customer requires, correctly, the first time.Start a process to meet the customer's request, rather than to build inventory.Minimize variations to ensure repeatable quality.Use statistics: take samples and analyze for variations.Investigate and document the business process, including inputs and outputs.Look at the problem from the customer's point of view.Select projects to maximize financial improvement but define a limited project scope.A Summary of Six Sigma Project Methodology "Lean" and "Six Sigma" methodologies seem quite different, but a company can benefit by wisely uniting these approaches. ![]()
