This book provides important guidelines for digital transformation and demonstrates how established companies can not only recognize emerging opportunities and risks early on but also systematically leverage them for their strategic development. New technologies, new project management tools, new leadership ideas, new business models, and new organizational concepts are available, which start-ups naturally utilize from the outset. In contrast, established companies require comprehensive change management to exploit these new possibilities as early and extensively as possible. The Toolbox for Digital Business helps you become an active shaper of change. (Almost) everything a successful CEO and CDO needs for a successful digital transformation: inspiration, best cases, tools, and enjoyable reading! In our Bitkom study "Last Call Germany," we presented visions of how Germany could position itself in Europe if we act consistently. In this work, you will find valuable impulses and instruments to achieve a convincing positioning—especially through entrepreneurial action! The path to digital excellence not only involves new technologies but also requires visionary thinking and a thorough, philosophy-aligned engagement with core topics such as leadership, change management, and digital business models. This book offers practical, essential impulses and indispensable tools and concepts for anyone involved in digital transformation processes in companies and organizations—forming the foundation for sustainable business success in the digital age.
