International Lean certification – IIBLC Green Belt, Black Belt and Champion exams
You can also evidence Lean knowledge with an internationally recognised certification. At Szinergia, Lean certification can be earned in Hungary in an official IIBLC exam setting: as the first official Hungarian exam centre we organise Green Belt, Black Belt and Champion exams. IIBLC Lean certification is independent of training providers. Exams built on the common Book of Knowledge measure how well a candidate understands Lean thinking and methods, and at the higher levels how well they can apply them and lead improvement programmes.
