During the Six Sigma Measure Phase of the DMAIC cycle in the Six Sigma approach to problem-solving, we need to understand the degree of the process variation. The degree of process variation, as you will learn in Lean Six Sigma Green Belt training and also in some of the free Six Sigma courses, tells us how many […]
7 Steps to Create SIPOC Diagram in Six Sigma
In a Six Sigma project, the SIPOC diagram is one of the important tools in the Six Sigma DEFINE phase of the DMAIC framework. In Lean Six Sigma Green Belt course, and even in free Lean Six Sigma course, you will learn that it is an acronym that stands for Suppliers, Inputs, Process, Outputs, and […]
What Is Quality Function Deployment (QFD) and Why Do We Use It?
Quality function deployment is a LEAN technique that is a little out of scope for Six Sigma Green Belt practitioners and more useful for Black Belt practitioners. Yet, it is a powerful tool to design processes or products according to customer requirements. Quality function deployment is abbreviated as QFD. It fits into the Define phase […]
What is the Difference Between DMAIC and DMADV in Six Sigma?
Lean Six Sigma Green Belt training mostly focuses on the Six Sigma framework of DMAIC which is specifically designed for improving existing processes. But what happens if a process needs to be completely re-designed in order to bring improvement? While it is not often discussed in a brief free Six Sigma training, there is another Six […]
4 Types of Relative Measures of Dispersion for Six Sigma
The Six Sigma approach is data-driven. Therefore, Six Sigma practitioners who have got the Lean Six Sigma training or another Lean Six Sigma Green Belt course will know that Six Sigma teams are confronted with many different types of data in different units of measure. Relative measures of dispersion are measures of the variance of […]
