Thornley Group Black Belt training is conducted by professional trainers who are experienced as senior managers and Lean Six Sigma practitioners. After completing training, candidates will be equipped with detailed knowledge of how to apply Lean Six Sigma in their organisation to deliver structure process improvement projects.

Our Black Belt upgrade training provides all the information candidates need to lead projects and implement Lean Six Sigma. The course builds on the DMAIC and Lean principles at the core of these methodologies, but provides extensive training and focus on advanced statistical tools, data management and project management skills.

Thornley Group Black Belt training is aimed at professionals who oversee business improvement projects and have a responsibility for managing improvement teams.

Course instructors use their practical Lean Six Sigma experience, along with simulations and exercises, to take candidates through the process of applying the tools and techniques learned during training.

  • Black Belt candidates must have completed Green Belt training prior to attending this course. Green Belt certifications will be verified prior to attendance. Candidates who have received their training from other organisations are welcome to attend. But, due to inadequate coverage from some training organisations, we cannot guarantee that your prior certification is adequate for the Black Belt exam.
  • Candidates require knowledge of algebra and must be familiar with analysing numerical data, such as through Green Belt training.
  • It is recommended that Black Belt candidates have the authority to undertake a process improvement project in their organisation. This project should offer significant cost savings, defect reduction or have some other customer impact. Where it is not possible for candidates to take part in a project, Thornley Group will provide a simulation case study.
