Our Green Belt training gives an extensive grounding in Lean Six-Sigma which covers in detail: Lean tools and techniques and business benefits, project set-up, DMAIC and all the associated statistical tools and techniques. Thornley Group Green Belt training is targeted at people who spend a significant amount of time involved in process improvement. This could either be as a process owner or a member of a team working on an improvement project. After completion of this training you can be upgraded to a Black Belt certificate with only a further 5 days of training.

Using their practical experience of improvement programmes, along with simulation exercises, our trainers can take candidates through the process of applying the tools and techniques that they learn.

  • Candidates must have basic numeracy skills (See separate maths qualifier test on our resources page).
  • Candidates should ideally have the authority to work on a project in their organisation as this will improve credibility with prospective employers. This should be a cost saving, defect reduction or other customer impact project. Thornley Group will provide a simulation case-study where this is not possible.
