The cornerstone of lean thinking is the continuous search for and elimination of waste, with the goal of producing more while consuming fewer resources. \u201cLean thinking\u201d can be viewed as an evolution of previous organizational models, successfully integrating them into a coherent business system. The results are of this magnitude: productivity +100%, reduction in lead time, inventory, and errors by 50%, and so on. This essential and rigorous book reads like a novel; it is aimed at Italian companies, features Italian case studies, and highlights key figures close to home. It therefore leaves no room for excuses from those who might be reluctant to apply these principles, claiming that \u201cit can\u2019t be done here\u201d or \u201cthings are different here,\u201d and so on. It can therefore be used by specialists as a reference text, but above all by entrepreneurs, managers, students, and anyone who, whether out of professional or cultural interest, has the courage to think for themselves and make use of their own intelligence.<\/p>\n
