industries Six Sigma doesnt remove the need for experienced leadership and it doesnt negate the importance of intuition in any process Instead Six Sigma works alongside other skills experience and knowledge to provide a mathematical and statistical foundation for decision making

Basically the SMED methodology consists of 6 steps: observe the current changeover process identify internal and external activities convert activities from internal to external setup increase efficiency of the remaining internal activities optimize the Startup time increase efficiency of external activities Theory of Constraints

Divide the sum from step five by the sum of the weighted totals from step three. In this case, 59.4 / 18.1 = 3.28 7. The answer from step 6 is the score for your project.
Here are Six Sigma’s fundamental principles: Y = f ( X) + ?: All outcomes and results (the Y) are determined by inputs (the X s) with some degree of uncertainty (å). To change or improve results (the Y), you have to focus on the inputs (the X s), modify them, and control them. Variation is everywhere, and it degrades consistent, good performance.

Often, Six Sigma improvements address processes that are out of control. Out of control processes meet specific statistical requirements. The goal of improvement is to bring a process back within a state of statistical control.
