Globalization, digitization, global supply chains and the Corona pandemic have led companies to take a closer look at value chains. Shifting services to partially competing supplier networks is giving rise to new guiding principles, strategies and processes. The focus in the future has therefore long since shifted from leveraging internal cost advantages to information exchange, stable supply chains and the exploitation of global cross-company potential.This book uses innovative, digital and strategic examples to show how successful supplier management must function and act.
