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

Certify your ability to:

  • Work effectively with, or as a member of, a process improvement team working in an environment supporting Lean Six Sigma.
  • Analyse and refine processes to improve efficiency and remove waste using Lean.

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. By completing the practical assessments, you will be recognised as a ‘Lean Six Sigma Certified Green/Black Belt’. This certified status is valid for 5 years, when a reassessment will be required in order to maintain your status. 

Individuals are not required to start at Yellow Belt and work their way up through the Belts; you can enter at any Belt level. However, the Green and Black Belts are aimed at individuals with prior experience in the field of process improvement and have a statistical background.
