The principles of Scrum provide a company with perhaps the most important capability to succeed in today's world: agility. With the help of a few clear rules and methods, self-organized teams achieve above-average results. Consistent solution orientation, clear responsibilities, user involvement, flexible planning adjustments, and flat hierarchies are central aspects. The authors elaborate on Scrum as a principle of organizational development, providing a fundamental practical guide for managers and change managers. The practical guide demonstrates how Scrum can be integrated into organizations step by step, supported by illustrative graphics and sketches for their own workshops.
