In this post, we will look at the step by step approach to perform Attribute Gage R&R. It is also referred to as Discrete Gage R&R. We will also explore the results of Attribute Gage R&R and how to interpret these results. In my earlier post, we looked at what Measurement System Variation means, how […]
Non Normal Data : How to deal with it?
One of the most common question that I get while mentoring GB/BB projects as well as while training LSS belts is “What should I do when I have non normal data?” Normally distributed data takes a center stage in statistics. A large number of statistical tests are based on the assumption of normality of the data, which […]
Measurement System Analysis (MSA) overview
In this post, we will talk about Measurement System Analysis, commonly referred to as MSA. We will also look at which Measurement System Analysis you should perform depending on the type of your Lean Six Sigma project data. And we will talk about the important terms in an MSA along-with the pre-work needed before you […]
What is Measurement System Variation?
I will talk about how variation can crop into your data because of a faulty measurement system. And how you can ensure it doesn’t happen before you analyze the data set. Traditionally, Lean is used to remove any and all types of wastes in your processes, and Six Sigma is used to remove variation from […]
12 Essential things you need to do in DEFINE stage of your DMAIC Project – Overview
This post covers the essential tools which should be used in DEFINE stage of your DMAIC project. But even before you start with any Lean Six Sigma project, there are 3 things that you need to be careful of. What to do before you start a DMAIC Project? First, it’s important that we identify the […]
What is Variation in your process and how to identify variation
This post is about process variation. In the last post, I talked about what a process means. A process will have some suppliers, who provide inputs to the process, and customers, who uses output from it. All the steps or activities that are done on the input to convert or change it into desired output […]
What is a Process…? And how do you represent a process…?
Before we get into the details of Lean Six Sigma (LSS), it is essential to get familiar with the various terms and jargons that will keep repeating themselves in this journey. Everybody will normally be familiar with these terms, however, it is important to understand the same from the process improvement standpoint. So, I intend to […]
