![]() This is essential, especially on projects that take longer to complete. So apply it accordingly, and address those areas which have not responded to simpler tools. The other day I read a post where someone described Lean as wide, and Six Sigma as deep. Using Six Sigma approach for the right projects. It is about making the tool work for you (not the other way round)!īelow are a few things I feel are important to help you gain the benefits from the application of Six Sigma (not an exhaustive list): The emphasis is on achieving the benefit sought. In a nutshell (still intact), it works like this: you use only the tools needed in order to achieve a sustained improvement result. Other times I have been very frustrated with it, and thought to myself, the answer is so obvious, why am I going through all these steps when I could achieve 80% of the outcome with a lot less effort? Why am I using a sledgehammer to crack a nut? And this love/hate relationship has made me amend my approach into what I would like to call Benefits Driven Six Sigma. It can be elegant and powerful in solving difficult problems. I would describe my relationship with Six Sigma as love/hate. In fact, I would almost go the other way and say that most people I have worked with are put off by the perceived rigidity and often overly meticulous approach of a blue blood Six Sigma project. Participation in the culture of improvement? Yes! But nitty-gritty Six Sigma? Not in my experience! The magnitude of K depends on specimen geometry, the size and location of the crack or notch, and the magnitude and the distribution of loads on the material.Open many a Six Sigma handbook and it will tell you that ‘Six Sigma is for everyone’. The concept can also be applied to materials that exhibit small-scale yielding at a crack tip. It is a theoretical construct usually applied to a homogeneous, linear elastic material and is useful for providing a failure criterion for brittle materials, and is a critical technique in the discipline of damage tolerance. In fracture mechanics, the stress intensity factor ( K) is used to predict the stress state ("stress intensity") near the tip of a crack or notch caused by a remote load or residual stresses. ![]()
