Lean Six Sigma

Lean Six Sigma is a management approach to business performance improvement that has blended the two individual specialisms of Lean and Six Sigma.

The application of Lean Six Sigma allows quality and efficiency improvements to be effectively realized. The focus of Lean is about speed, efficiency and taking waste out of a process. Six Sigma focuses on effectiveness and removal of errors.

When combined and implemented properly it can be a powerful management tool that can greatly improve an organization’s performance, by providing a structured approach to resolving problems.

All of the Lean Six Sigma belts are available in English

What’s involved?

Yellow and Orange Belt certifications involve a multiple-choice exam.

Green and Black Belt certifications consist of a theory exam and practical assessment.

This certified status is valid for 5 years, when a reassessment will be required in order to maintain your status.
