SIX SIGMA – A POWERFUL TOOL TO IMPROVE BUSINESS PROCESSES
4. March 2019
You only think of karate when you hear “green belt” or “black belt”?
After reading the comprehensive paper on Lean Six Sigma, you will know better. Also, PDSA cycles and DMAIC roadmaps won’t be new to you anymore. But first, let’s start off with a short introduction into Lean Six Sigma and what it can do for you and your company
Probably all of us have at least once flown with an airplane, from one location to another one, at a regular speed of 580 mph ~ 933 km/h and at altitude of 38.000 feet ~ 11.582 km. We sat next to the aircraft window, reading a book, working on our laptop or just sleeping. Have you ever thought of what kind of quality tests this window next to you as well as all the other parts of the aircraft have been through in order to guarantee safety for human life?
Lean Six Sigma and its pool of different tools make this be possible to happen.
Generally speaking, a majority might be aware that Sig Sigma exists, but what you most people are not aware of, is how close they are in contact with LSσ in their regular daily activities.
Lean Six Sigma brings together two sets of methods, principles and tools that complement each other. While both approaches aim at reducing waste and defective outcomes, “Lean” has a stronger focus on increasing speed, while “Six Sigma” mainly deals with producing predictable outcomes and reducing variation.
One can view Lean Six Sigma from various angles:
• A statistic for assessing capability
• A methodology for improving the organization
• A management philosophy
Getting back to our initial example – for example, in the area of quality testing, the Six Sigma level (6σ) defines a process that is producing 3.4 defects per million opportunities for that defect to occur (this is 99.9997% defect free). You would want at least this security level for the aircraft windows, wouldn’t you?
