Instructor: Brianna Whiting
There are many training courses that employees can take to help strengthen the operations of a company. The focus of this lesson is Six Sigma and the training that helps employees reach a variety of certification levels.

A First Look at Six Sigma

Meet Wyatt! Wyatt works in production and has decided that he would like to be given more responsibility at his company. He feels that it is time to make some career moves and find some opportunities for advancement. After talking to some of the executives where he works, Wyatt feels the best way to accomplish his goal is to become more familiar with Six Sigma.

Six Sigma is a methodology for trying to reduce and eliminate defects and variations in the many processes of a company. Because he works in production, Wyatt knows that becoming certified in Six Sigma practices would not only benefit the company, but would give him the tools he needs to be considered for a promotion. Let's take a look at what Wyatt found out about Six Sigma.

Six Sigma Further Defined

Wyatt first starts with wanting to know a bit more about the basics of Six Sigma. He finds out that this type of method helps a company strengthen processes and produce more consistency in output. The objective is to make sure a company is producing the highest quality outputs by removing the factors that cause defects or variations.


When an individual like Wyatt decides to start training in Six Sigma, he or she will learn how to develop projects that follow specific steps in order to achieve results. Those steps are focused on reducing the costs and times associated with processes, reducing pollution, improving satisfaction of customers, and helping to increase profit. Certification at the many Six Sigma levels requires leading projects and passing exams.

Wyatt will also be trained on how to use steps known as DMAIC. DMAIC stands for define, measure, analyze, improve, and control. This means when Wyatt is implementing Six Sigma, he will define the problem, measure its effects, analyze how to correct it, correct or improve it, and then maintain or control it so that the company continues to operate smoothly.

Wyatt's training will include how to use DMADV as well. DMADV stands for define, measure, analyze, design, and verify. Wyatt will define what the goals are for the project, and measure what the customer needs. He will then analyze the options to meet the needs of the customer. This is followed by designing the process to meet those needs and verifying that the design actually met the needs.


While Six Sigma training can be a valuable asset for Wyatt, he realizes that he cannot simply take a course and then be ready to handle any problem his company faces. You see, Wyatt has to move through a variety of courses and training in which he will receive certifications after successfully passing. The very first certification he will face is Champion certification.

Champion certification is the most basic of all the certifications and will provide Wyatt with the basic knowledge of Six Sigma. Champions do not have the quantitative skills to participate as Six Sigma project team members, but because Champions are usually executives in their companies, they are able to remove any obstacles that may hinder a Six Sigma project and can provide resources. They also help develop objectives of projects and are instrumental in finding leaders to lead project teams.

Green Belts are the next level of certification, and when Wyatt achieves this level he will be able to begin leading simple Six Sigma projects. Green Belts usually work on projects part time and often include managers within their organization. Green Belts help select project team members, analyze data, and help train members on Six Sigma practices. In order for Wyatt to advance in certification, he must obtain Green Belt certification first.
