Figuring out what tools to use during the course of a Six Sigma project is a challenge. Not all tools will be used on all projects. The analogy I use in the classroom is a mechanic with a toolbox. In the tool box are different types of tools – screwdrivers, wrenches, pliers, and so on. […]
Frequency of measurement is an issue that we often grapple with when evaluating and improving performance. Today we will discuss how often we should collect and analyze performance data. There is a trade-off to be made between the time and effort to collect data frequently, and the lack of knowledge and feedback that result when […]
In our Green Belt program we have an exercise where students create a histogram from a set of data. Most students use Excel to create their histogram, and here is the resulting graph: When submitting their work, students quite often include a statement to the effect that the data is “normally distributed” because it appears […]
One of the dilemmas that students face when choosing Six Sigma certification training is whether to attend a live, instructor led course in a traditional classroom setting or an online course. Both types of delivery have pluses and minuses. In the classroom, you will have the benefit of interaction with your instructor and the other […]
I have observed a number of problems and issues with the way that Six Sigma students gather data for, create and interpret control charts. The purpose of this article is to help you avoid these common problems and issues, and to help you understand how to use control charts as part of a Six Sigma […]
The Six Sigma methodology relies on decisions that are made based on facts and data. One of the challenges in the Analyze phase of Six Sigma is being able to identify what is really going on in a process based on the facts and data that were collected in the Measure phase. Another challenge is […]
I am often asked to provide recommendations on how to develop and/or select Six Sigma training programs. An interesting and very useful theory of how people develop and learn is the theory of Multiple Intelligences, developed by Howard Gardner, PhD, Professor of Education at Harvard University. This theory explains that each of us has a […]
