Improving business performance involves many steps.

The first step to process improvement is making the commitment to changing the way you do business.

The Thornley Group Lean Six Sigma Green Belt Course covers all Lean Six Sigma principles in detail. The training programme includes all Lean tools and techniques, as well as their benefits to the business. Candidates study the central DMAIC principles in depth, combining them with education on project set-up and statistical tools and techniques to deliver successful process improvements. Thornley Group Green Belt training is aimed at professionals who spend a significant amount of time involved in business improvement. Green Belts are often process owners, team members or even team leaders. Following Green Belt training, you can be upgraded to a Black Belt certification with only a further 5 days of training.

Our trainers use their practical experience with Lean Six Sigma projects to take candidates through the process of applying the tools and techniques they learn as part of the Green Belt course.


Candidates who complete the Thornley Group Green Belt course are eligible to take the NZOQ or IASSC Green Belt exam. It is also recommended that candidates participate in an improvement project that delivers cost savings, reduces production defects or improves customer satisfaction. Thornley Group provides email support for 6 months after completion of the Green Belt course to help candidates achieve their projects.

  • Candidates must have basic numeracy skills (See the maths qualifier test on our resources page).
  • Ideally, candidates should have the authority to work on a project in their organisation. Applying the knowledge gained from the Green Belt course will cement the lessons and improve credibility. The project should be cost-saving, defect reduction or have other customer impacts. We will provide a simulation case study where a real project is not possible.
