How can companies respond economically and sustainably to customer needs in the age of digitalization? Why does the structure of a company play a significant role in achieving value creation and genuine effectiveness? The authors explore these two questions. At the same time, they provide the reader with a tool in the form of a 7-step methodology that can sustainably transform a company's organization. Their theses and methods are structured, comprehensible, and vivid, supported by numerous graphics and the metaphor of the "wave of effectiveness." Many examples from corporate practice round out the work and give it the relevance it deserves.
