The book provides a compact overview of the increasingly important topic of Business Development (BD). The author not only describes the role of the Business Development Manager and its tasks, but also shows how Business Development can be integrated organizationally into a company. In addition, a prototypical Business Development Process is presented in concrete terms and explained using a case study. The book shows why enterprises fail, deals with new creative techniques such as Hackthons and dedicates itself more comprehensively than so far to the topic of communication in the course of changes. The book helps all, which want to introduce and/or optimize Business Development in the enterprise as responsible ones or work in the future in this range.
