About this Book Many large enterprises are facing pressure from the rapid dig- italization of the world: “digital disruptors” attack unexpectedly with brand-new business models; the “FaceBook generation” sets dramatically different user expectations; and new technologies have become available in the cloud to everyone with a credit card. This is tough stuff for enterprises that have been, and still are, very successful, but are built around traditional technology and organizational structures. “Turning the tanker”, as the need to transform is often described, has become a board room-level topic in many traditional enterprises: “we need new digital products!”, “we need to renew our tech stack!”, “we need to de-layer our organization!”, “we need to become agile!”, “we need to become digital!” are the battle cries that often emerge out of the board room.
