Mergers and acquisitions represent a popular form of growth in the logistics industry. The achievement of the goals pursued by these mergers is primarily dependent on post-merger integration, which involves the strategic and structural incorporation of the acquired logistics company into the purchasing company. Due to the characteristics of these service providers, there are some specific requirements that arise. Harald Bachmann develops application-oriented methods and tools for the integration of logistics service providers within the framework of a theoretically grounded analysis. A two-stage empirical investigation focuses on the practical application of these approaches. In the first step, a comparative field study examines individual activities in various integration projects of logistics companies. This is followed by two comprehensive case studies.
