Companies are increasingly developing into dynamic and project-oriented organizations. Globalization, innovations and organizational dynamics require more and more projects, and thus a more project-oriented corporate organization and management. As a rule, managers as well as employees already work parallel to their line function in projects or completely from project to project. At the same time, cross-company and especially international value chains lead to the cooperation of cross-departamental and intercultural teams. For this, the specialists and executives need above all knowledge and experience in project management and the corresponding concepts as well as in the special form of cooperation, team development and communication. Because the most problems in project management are not caused by project goals and methods, but by the many different problem-solving behavior and attitudes, e.g. between engineers and business people, different departments or the different country cultures. The international IT project specialist Tom DeMarco puts it in a nutshell (in Peopleware - Productive Projects and Teams: The major problems of our work are not so much technological as socio-logical in nature. In terms of content here, in contrast to traditional professional textbooks, not only the technologies are priority, but also the social and intercultural aspects of project work. The book is aimed equally at students of all disciplines with a focus on managerial and project-related work as well as practitioners and entrepreneurs in all private business sectors as well as in NGOs, public projects or PPPs as public-private partnership.
