The program is built on a step-by-step approach. This means that a candidate has to start at the Green Belt level and can built his way up to the Champion certificate.

A candidate is not obliged to go all the way to the champion level. The members of the IIBLC® Content Committee have composed one single reference guide which is referred to as 'Book of Knowledge'. This Committee will continuously adapt and update this book in order to keep track of recent evolutions and trends in the field of Lean. The Book of Knowledge mentions the curriculum outline and all reference books that encompass this content. This book is an indispensable item during your preparation and can be purchased from PMI. Please contact us!
