Because supplier networks are becoming increasingly wide-spread as more suppliers across the world become available to the industry (some in countries that are not covered by recognised national and inter- national authorisation), early identification and management of those supply chain risks that could affect product/service quality becomes increasingly necessary. The application of supply chain risk management provides business protection by ensuring the continued success of the customers supply base in delivering products/services in accordance with programme and quality requirements.Supply chain risk awareness should be part of an integrated business culture.This document may be used as an "aide memoire" to supplement the existing risk management philosophy of the user.
