Six Sigma Green Belt: Project Examples

Instructor: Brianna Whiting
There are many different levels of Six Sigma. This lesson focuses on the Green Belt certification and the projects they might take on for their company.

What is Six Sigma?

Companies always want to cut costs. But what is an effective way to do so? While there are many ideas that may come to mind, one method many companies are turning to is Six Sigma. Six Sigma is the process of trying to remove any variations or defects in the processes of a company. Defects cause a company to have to correct or replace defective products which cost a company money. So, by implementing Six Sigma, a company is able to remove or at least reduce their wasteful practices. This is done by means of projects and are completed by those that hold a certification of Six Sigma. Come along as we look at some project examples of Six Sigma, particularly those projects of individuals that are Green Belt certified.

Green Belts

So you may be wondering what a Green Belt is? Well, a Green Belt is someone who has been trained in Six Sigma practices and can help lead improvement processes and projects. Green Belts are responsible for leading projects part time. They understand basic Six Sigma calculations and are instrumental in assisting with collection of data. Because Black Belts are the next level of certification, Green Belts help Black Belts when needed.

Projects for Green Belts

Now that we know what a Green Belt is, let's take a moment to look at some potential projects for that level of certification.


There are many characteristics that a good Green Belt project possesses. First, projects should improve processes that are already being implemented. This means taking activities that are necessary to create an output and making them better. Next, the project should address quality issues like defects, complaints by customers, lost time, returns, and even extra inventory. This ties into the third major characteristic of reducing waste. Waste can be anything like excess inventory, excess time waiting during a process, excess processing, and not using workers to their full potential.


A good Green Belt project will not only have input and output processes that are identified, but it will also never have a solution that is already determined. After all, if you already knew the solution, then there would be no need for a special project. The following are examples of possible Green Belt projects.

1. Reduce the amount of time to complete a process. For example, trying to find a way to cut one machine or make one machine do the function of both in order to reduce cost and wasted time.

2. Finding ways to reduce the amount of time to hire a new employee. If a company is shorthanded and needs another employee, every day that passes without hiring the much needed employee costs a company money and may even slow production.
