Identifying Data type for project metric sometimes can be confusing. In this post, we discuss how to identify data type for your Lean Six Sigma project metric. And more importantly, what mistakes to avoid. Before we start talking about the data type of your project metric, we need to understand base and derived metrics. It […]
Data Type for Lean Six Sigma Projects
Why is data type important? A Lean Six Sigma project will deal with a lot of data. The project owner needs to perform various tests on such data set. The statistical tests to be performed depends on the data type. Hence, its imperative to understand the data types for all the data sets you have […]
Continuous Gage R&R – A Step by Step Approach
In this post, we will look at the step by step approach to perform Continuous Gage R&R. It is also referred to as Gage R&R. We will also explore the results of Continuous Gage R&R and how to interpret these results. In my earlier post, we looked at what Measurement System Variation means, how it can creep […]
Lean Six Sigma Project Metric – Common Pitfalls and Best Practices
Selecting the right Project Metric is crucial for Lean Six Sigma projects. In this post, I will talk about how to correctly identify, scope and define the Project Metric for your LSS Project. And most importantly, how NOT to. This is based on the insights drawn from a plethora of projects that I have led, […]
Attribute Gage R&R – A Step by Step approach
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 […]
