Lean Six Sigma Green Belt: Is It Right for You?

Green Belts carry the language of Lean Six Sigma deeper into the organization, driving culture change in how the organization sees problems and in its approach to solving them.

Six Sigma is a problem-solving methodology and data-driven approach to reducing process variation. Lean is a complementary improvement and problem-solving methodology that strives to reduce or eliminate activities that don’t add value to the customer.

Today’s Green Belt practitioners need to be well-versed in both as process improvement activities require aspects of both. Together Lean and Six Sigma are a powerful combination for improving process performance and instilling continuous improvement throughout your organization.

Lean Six Sigma Green Belts are often part-time resources, dedicating 25 to 50 percent of their time to Lean Six Sigma activities. They implement smaller-scale projects that have direct impact to daily duties. They also assist Black Belts with team activities and tool application.

To become a Green Belt, people usually go through a training and certification process that covers a body of knowledge, quizzes and exams, and a project for real-world application. Green Belts should be skilled in the DMAIC methodology (Define-Measure-Analyze-Improve-Control) and principles of Six Sigma, as well as in-process mapping, root-cause analysis, and basic statistical analysis.

Green Belts are also instrumental in spreading the language of Lean Six Sigma, when discussing processes, data, maps and metrics, throughout the organization. They become local advocates, supporting improvement efforts through data-driven decision-making and accelerating the number of employees positively affected by Lean Six Sigma. To help in this endeavor, Green Belts also benefit from change leadership and facilitation skills.

Which format is better: classroom, online or blended?

Classroom courses provide the advantage of in-person time with your instructor and a mix of classmates from all industries and a range of locations, which provides a great chance to network with like-minded problem-solvers and build lasting relationships. The classroom also offers many interactive and experiential activities, discussion and mock simulations of real-life business scenarios.

Online learning offers a flexible, cost-effective method for skills development, featuring the same world-class curriculum as our classroom versions, with engaging visual content, animated modules, activities and real-world case studies delivered in a pure HTML format so you can access it across desktop and mobile devices. Please note: for individuals interested in our online training, certification is not included.
