In this post, we will talk about Nominal Group Technique, commonly referred to as NGT. Nominal Group Technique is a structured method of brainstorming, where the participants come with ideas on their own rather than as a group. And then, the group collectively evaluates, ranks them according to their importance and agree upon these generated […]
Normal Distribution for Lean Six Sigma
Normal Distribution, also called Gaussian distribution, is arguably the most important distribution from a statistical analysis perspective. As a Lean Six Sigma practitioner, one needs to understand this distribution, its characteristics and applications in the projects. We will look at all the details pertaining to Normal distribution and its application in Lean Six Sigma. Read […]
Probability Distribution for Lean Six Sigma
In this post, we will look at what Probability is and its application in Lean Six Sigma context. We will also talk about discrete and continuous Probability Distribution and look at their characteristics. Before we delve into probability distribution, lets take a quick view of basic Probability concept in general. What is Probability? You must […]
Histogram – Identifying Shape of the Data
Histogram is a graphical analysis tool used to identify the shape of the data. In this post, we will discuss various characteristics of a histogram, how to identify shape or distribution of your data set using histogram and how plot a histogram using Minitab as well as excel. What is a Histogram? Histogram is a […]
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 […]
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 […]
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 […]
