About Lean Six Sigma International

One standard. Proven expertise. International reach.

Lean Six Sigma International is an international Lean Six Sigma organisation developing standards, training and certification, built on the experience and expertise of Lean Six Sigma Belgium and Lean Six Sigma France.

In France, training activities within the applicable certification scope are delivered by Lean Six Sigma France, a Qualiopi-certified training provider.

Our ambition

Unlocking the full potential of Lean Six Sigma
Our ambition is to develop professionals capable of unlocking the full potential of Lean Six Sigma and turning it into meaningful and lasting value.
The LSSx.0 standard, developed from our experience in practising and teaching Lean Six Sigma, provides the framework for this ambition — building the knowledge, practical capabilities and structured thinking practitioners need to apply Lean Six Sigma effectively.

Qualified LSSx.0 Trainers

Consistent quality also depends on the people delivering the training.
We select experienced professionals with strong practical backgrounds, then train and certify them according to our requirements before accrediting them as LSSx.0 Trainers.
Only accredited LSSx.0 Trainers are authorised to deliver our programmes, helping ensure consistent, high-quality delivery across countries and learning formats.
