Supply chain managers must contend with numerous complex and often baffling issues. External events – such as strikes, natural disasters or terrorism – can slow or stop their operations. These are the managers who must plan for supply chain disruptions, and who are front and center when they happen. Logistics expert John Manners-Bell ably provides an A-to-Z report – often hair-raising, never dull – on the hazards inherent in supply chains and how to manage or minimize them. getAbstract recommends his cautionary insights to supply chain managers, their bosses and their suppliers to aid risk planning and risk mitigation.

Consider this scenario: A road-freight operator delivers an essential manufacturing component one day past its scheduled arrival. Not having it on time halted production, which caused missed sales and idled factory workers. Who or what is responsible?
