In recent years, many companies have reduced their value-adding activities and implemented efficiency-oriented cost reductions, e.g. outsourcing, single sourcing, low-cost country sourcing, platform concepts, lean management, design-to-cost approaches. This giving the purchasing function a significant role in any enterprise. As a consequence SRM has become more important and is aimed at building resilient supply chains. Resilience is based on being able to anticipate, manage and prevent supply chain disruptions at an early stage. On the other hand, supply risks have risen due to increased dependency on supplier networks. Supply disruptions can easily lead to high recovery cost, waste and sharp decreases in sales, as pointed out in the present study. External customers become dissatisfied and internal core functions (e.g. assembly) are disturbed. In most cases, supply disruptions have negative impacts on brand image, sales figures and the company's own financial situation. Although literature is already available on the topic, both top management and academia underline the need for a more holistic approach towards SRM. This book outlines, based on the doctoral thesis, 15 best practice and industry excellence categories in SRM for manufacturing companies in the European transportation industry. It also shows a model, how to implement these best practices. Dr. Marc Helmold has been working in industry and academia.
