Companies face the constant challenge of successfully asserting themselves in the market and responding to changing conditions, whether in specific areas or more broadly. If those responsible for managing these so-called transformations are not experienced, they must gather the necessary foundations from various sources – the scientific basis of business administration, research on transformation processes, and practical experiences from the economy. While there are books on corporate and business field transformation (Business Transformation), they mostly describe only parts of a transformation and are often not very action-oriented. This book aims to provide the reader with orientation and practical assistance in the diffuse terminology surrounding restructuring, change management, and transformation. It defines the concept of Business Transformation and describes an application-oriented guide based on the process of strategic management for effective strategic realignment and organizational transformation of companies and business fields. Complemented by checklists in each chapter, it facilitates easy implementation in practice. It is intended for entrepreneurs, executives, project managers, works councils, and students who are involved in the realignment of and within companies.
