With supply chain disruptions increasingly discussed in the media and impacting our daily lives, Flow offers an important framework and solutions for remedying the rampant delays and bottlenecks that exist in global supply chains. This book describes the concept of flow, which evokes physical properties that exist in nature, such as the flow of electricity, the flow of materials, and the flow of time. In terms of process optimization, flow encompasses the integration of end-to-end supply chains and the movement toward relocation of global supply bases to nearshore/onshore geographies. Achieving flow is essential for organizations seeking to improve their supply chain performance in a time of increasing disruption. This book highlights the high-level effectiveness of business strategies that use predictions based on the sequence of world events, global supply chains, and data by exchanged smart technologies. By broadly applying physical laws to the global supply chain, Rob Handfield and Tom Linton explore the impact of supply chain physics on global market policies, such as tariffs, factory location, pandemic response, supply base geographies, and outsourcing. The authors provide specific recommendations on what to do to improve supply chain flows, and include important insights for managers with examples from companies such as Biogen, General Motors, Siemens, and Flex with regard to their response to COVID-19. Flow is an important resource not only for procurement and supply chain management professionals, but for any manager concerned with enterprise-level success.
