Kaizen is a Japanese method for continuous improvement which involves the entire corporate structure. The term is in fact composed of the words kai (change) and zen (better).

Initially presented by Toyota and increasingly embraced around the world, the kaizen method is based on the principle that sets the basics of this philosophy: "energy comes from below", which means that in a business, results are not obtained by management but thanks to the direct work on the product. Management then acquires a new function, not tied to hierarchical management but rather supporting staff directly involved in production.

Itlas has been using the Kaisen method since February 2009: the first workshop concerned the application of the principles to the sawmill department for the production of wood strips. Since then, four days a year, employees from all departments gather together and make suggestions that can benefit production processes.
