“Six Sigma is a quality program that ultimately improves the customer experience, reduces costs, and creates better leaders”

Jack Welch, Former CEO of GE

## Who is it for?

**Lean Six Sigma Green Belt certification** is issued to Six Sigma professionals who work closely with Black Belts, who are responsible for most of the Six Sigma data collection. As this methodology is highly statistical in nature, it is of the utmost importance to start with a complete set of valid and accurate data. Green Belts are usually employees of a Six Sigma company who also have other day-to-day responsibilities within that company.

Occasionally, a Green Belt may also fill minor leadership roles within a Six Sigma team, particularly for small-scale projects. They are well educated in the proper use of Six Sigma tools and employ them under the direction of a Black Belt project leader.

## Course information

#### Face to face

At the customer

#### Remotely

Online

#### Duration

40h, or 5 days

#### Final Test

2h, 100 questions

#### Formats

We think that the blended mode has several advantages from the point of view of flexibility, costs and practical exercises and is therefore recommended above all for company training groups.

#### Training Material

The teacher will provide students with the slides necessary for learning the theoretical part. In addition, he will provide a manual as additional support material.

For the entire duration of the course, the teacher is available to answer any questions or doubts via email, or by setting up a short videoconference with the student.

For the practical part, the student will have free access for 30 days to the Minitab statistical software. In addition, the teacher will provide a series of spreadsheets in Excel format for carrying out some exercises.

#### Duration

**The course has a total duration of 40h (or 5 full-time days)** to which it is recommended to add at least ten hours for individual study and exercises.

#### Project

**At the end of the course, each student will have to present a short project** in which the methodology and some of the main Lean Six Sigma tools are applied. The project will then be discussed with the teacher.

#### Test methods

The exam can take place in written form (in person) or in digital format (remotely) by accessing a dedicated platform. The student will have to answer a series of **100 questions in a time limit of 2 hours**. To pass the exam, the student must correctly answer at least **70%** of the questions.

#### Cost

Costs vary by format (face-to-face or remotely) and by groups. We also provide individual courses on request.
