Introduction Lean Six Sigma Green Belt

LEAN SIX SIGMA GREEN BELT MASTERCLASS

What is this Lean Six Sigma Green Belt course about?

LEAN SIX SIGMA GREEN BELT MASTERCLASS

How do we define defects in Six Sigma? It's not the same as in everyday language. In Six Sigma, we have a broader definition of 'defect.'

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Six Sigma is not magic. It achieves ends by means of a Six Sigma project, which goes through distinct stages, namely DMAIC (Define, Measure, Analyze, Improve, Control).

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Six Sigma is a project. In each phase of the project, there are tools to help you. The mastery of these tools can be expressed as a belt color. So what is a Six Sigma white belt or black belt? Let's see.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Where does the 'six' in Six Sigma come from? Do we also have five sigma or four sigma, or just six sigma? The answer is yes, we do have those and we will explain what the number means.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Sometimes you hear Lean, sometimes you hear Lean Six Sigma and sometimes you hear Six Sigma? What's the story there? Are they all the same, or are they different?

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Six Sigma and Lean are not the same. When you learn Lean Six Sigma, you are not mixing 100% of Lean with Six Sigma, but rather just helpful parts of Lean with the standard Six Sigma curriculum. Let's learn more.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

A six sigma project starts with the define phase. What happens in the six sigma define phase? Well, we define relevant foundations of our six sigma project. Think of timeline and needed resources.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

You want a your six sigma project to be clear. All involved should know what the six sigma project is about. So you need to formulate a clear problem statement in the define phase of six sigma, without ambiguities.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the define phase of six sigma, we define a clear problem. But a clear problem should be accompanied by a clear goal. So, in the define phase of six sigma DMAIC, we also need to formulate a goal. The goal of our six sigma project should be measurable in terms of amount and date.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the six sigma define phase, we also define our six sigma project's timeline. The critical path method is a robust and useful tool for that purpose. It shows the timeline, but as an added value, it shows ius where we have buffers and where not. As a six sigma project leader, you should put your most experienced people on those parts without time buffer. Why? Let's see.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Normal distribution is sometimes a condition of certain data analysis techniques that we use in a lean six sigma project. Let's learn more.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the define phase of our six sigma project, we define our timeline. We can use the critical path method for that, or a Gantt chart, which is much easier to make and interpret. So which one of these two tools is more useful in our six sigma project? Both. Each has its own audience, so you use both of them in your six sigma project.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the six sigma define phase, we draft a project charter to sum up relevant macro level information about our six sigma project to the various stakeholders. A project charter consists of one page.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

So this concludes the lean six sigma green belt define phase. Let's sum of the tools and techniques we have learned and how they help us in this part of our six sigma project.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

Welcome to the measure phase of the six sigma project. In the measure phase of your six sigma project, you collect as much data as possible, related to your problem. At this point of the six sigma project, you obviously do not know for sure what is relevant. So, collect as much data as you can in this part of the six sigma project and throw away later.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

A lot of the data you will collect as a six sigma practitioner will be vague and poorly defined in technical terms, if it comes from human respondents. In six sigma, we refer to that type of vague data as VOC. But in six sigma, we like to work with well defined, technical information. So we need to translate this raw VOC into something we can work with in our six sigma project, namely CTQ factors.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The data you collect in the measure phase of a six sigma project has to be analyzed. Not all of the tools in your lean six sigma toolbox can be used on any type of data. Some tools in your lean six sigma toolbox can only be used with data measured on a certain measurement scale. Let's learn more.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The data that you collect in the measure phase of your lean six sigma project is used to find thee root cause(s) of your problem. This is done in the analyze phase of your six sigma project.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The data that you collect in the measure phase of your lean six sigma project has to be analyzed. The most basic analysis in six sigma, is the analysis of central tendency (which one value can tell us something about the data?) and dispersion (how is the data distributed).

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the six sigma analyse phase, you identify the root cause(s) of your problem. In the improve phase of your six sigma project, you formulate a solution to the root cause(s) and thus the problem you are trying to solve with your six sigma project. DOE is just one of the many tools that a six sigma professional can use to formulate a solution for the root cause (of the problem). Please be aware of the fact that as a six sigma professional, you may use tools like this, but you do not have to. We discuss some tools, it is up to you as a six sigma professional to see which one fits to your specific context.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The data that you collect in the measure phase of your lean six sigma project is used to find the root cause(s) of your problem. This is the aim of the six sigma analyze phase. We can use OLS regression for that purpose. But we have a detailed and less detailed approach. In this part of your six sigma journey, we teach you a detailed approach.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

So what is the six in six sigma about? The six in six sigma refers to a sigma score. Let's learn more about this sigma score.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The quality of the data you collect in the measure phase of your six sigma projects should be consistent and reflective of reality. In six sigma, we use precision and accuracy as words to describe these two characteristics.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

So this concludes the six sigma measure phase of our lean six sigma green belt curriculum. Let's do a wrap up.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the six sigma analyse phase, you identify the root cause(s) of your problem. In the improve phase of your six sigma project, you formulate a solution to the root cause(s) and thus the problem you are trying to solve with your six sigma project. Poka Yoka is a principle borrowed from the Lean tool box. This Lean tool makes processes or products mistake-proof. Please be aware of the fact that as a six sigma professional, you may use tools like this, but you do not have to. We discuss some tools, it is up to you as a six sigma professional to see which one fits to your specific context.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The data that you collect in the measure phase of your lean six sigma project is used to find the root cause(s) of your problem. This is the aim of the six sigma analyze phase. Correlation analysis is a tool used by six sigma professionals to quickly get an overview of relationships in data. Once the six sigma professional has an overview of the relationships, the six sigma professional can decide to zoom in on a few interesting relationships and get more detail. For that purpose, six sigma professionals use OLS regression.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

In the six sigma analyse phase, you identify the root cause(s) of your problem. In the improve phase of your six sigma project, you formulate a solution to the root cause(s) and thus the problem you are trying to solve with your six sigma project. We can borrow some concepts from the Lean toolbox to help us come up with a solution. One of these includes the Lean visuals. Please be aware of the fact that as a six sigma professional, you may use tools like this, but you do not have to. We discuss some tools, it is up to you as a six sigma professional to see which one fits to your specific context.

LEAN SIX SIGMA GREEN BELT MASTERCLASS

The final phase of six sigma DMAIC is the control phase. The solution you formulated in the six sigma improve phase, has to stick, has to keep the problem under control. That requires monitoring. In the control phase of your six sigma project, you can make use of control charts to do precisely that.
