Lean and Six Sigma deliver business goals and objectives though the rigorous application of proven improvement methodologies.  Combining both these methodologies eliminates waste, increases value and reduces variation.
 By focusing on the customer and delivering benefits quickly it is possible to improve quality performance and profitability simultaneously.

Thornley Group Green Belt training is carried out by professional trainers who are experienced as senior management practitioners in both Six-Sigma and Lean. After 5 days of classroom training  you will sit the IASSC exam and if successful you will become an IASSC certified Green Belt.

Prior to taking the exam, there is a further 25 hours of study using your course manual and our online testing which will enable you to study all the subject areas, in a structured way, right up to your exam date.  Access is also provided to our online video-based training that provides a further 16 hours of study after attending the 5-day course.
