Practical and filled with numerous examples, this book serves as a toolkit for every project manager: from dealing with eroding goals to understanding the halo effect. The execution of projects is becoming increasingly complex, and new focal points in project management are being established, making a diverse range of methods necessary. How can costs, reputational damage, and loss of image be avoided? This book discusses how complexity manifests in everyday project work and what strategies can be employed to address it effectively. In addition to theoretical components, examples from IT and energy supply are presented, illustrating aspects such as processes, stakeholders, and pitfalls.
