What is Six Sigma?The concepts surrounding the drive to Six Sigma quality are essentially those of statistics and probability. In simple language, these concepts boil down to, “How confident can I be that what I planned to happen actually will happen?” Basically, the concept of Six Sigma deals with measuring and improving how close we come to delivering on what we planned to do. What is LeanLean is a methodology that is used to accelerate the velocity and reduce the cost of any process (be it service or manufacturing) by removing waste. Lean is founded on a mathematical result known as Little's Law BenchmarkingBenchmarking is simple as a concept but much more involved as a process. The ultimate payoff is that you can become the best of what you do, and continuously improve upon that superiority. Scatter DiagramsTo control variation in any process, it is absolutely essential that you understand which causes are generating which effects. By knowing which elements of your process are related and how they are related, you will know what to control or what to vary to affect a quality characteristic. Quick WinsThis article reviews the criteria of a Quick Win, Just-Do-It, or No Brainer process improvement. Using Lean Six Sigma tools and methods we can identify the areas of opportunity to accelerate results, build project momentum, and create project buy-in. How to Identify and Select a Lean Six Sigma Black BeltLean Six Sigma Black Belts are most often referred to as Change Agents and there is no doubt that the Black Belt role is a leadership position within an organization. Black Belts are full-time Lean Six Sigma project team leaders responsible for implementing process improvement projects DMAIC (Define-Measure-Analyze-Improve-Control) or DFLSS (Design for Lean Six Sigma) within the business. Process SimulationProcess Modeling creates a simple simulated model of the process. You will visually see which projects will affect the total output and which will sub-optimize the system. Kano Model & Critical-to-quality TreeThe Kano model is based on the concepts of customer quality and provides a simple ranking scheme which distinguishes between essential and differentiating attributes. Elements of Measure (dmaic) & Prioritization MatrixOne of the goals of the Lean Six Sigma Measure phase is to pin-point the location or source of a problem as precisely as possible by building a factual understanding of existing process conditions. Chi-square Analysis for Attribute DataSteven Bonacorsi, Lean Six Sigma Master Black Belt writes about what is a Chi-Square test and the types of Chi-Square analysis. The author also discusses when to apply a Chi-Squared test and what it does, including test requirements and hypothesis. Lastly there are tips and tricks as well as guidelines for Minitab statistical software users.
