In the 2nd revised and expanded edition, the focus is on organisational aspects, inparticular the role of start-ups for the digital transformation, the design of the so-called Digital Innovation Units and the role of the CDO. Secondly, the design and management of digitisation projects is considered in more detail. And thirdly, the concept of digital transformation is further specified and delimited. In addition, the advancing technological development is taken into account. "Prof. Thomas Hess provides a concrete overview of many important aspects to be considered in the digital transformation of companies. Clearly worth reading." "Beyond the buzzword - Finally someone manages to systematically untangle the chaos surrounding digital transformation. With his book, Thomas Hess truly establishes the guardrails for managing digital transformation projects. While others promise much and deliver little, Thomas Hess gives the reader a design framework rather than a patent remedy."
