An interruption in the functionality of a system. Disruptions may be either internal or external. Internal disruptions may be due to human error, software error, or component failure. External disruptions may be caused by hostile attacks or natural phenomena, such as earthquakes, tsunamis, or hurricanes. Disruptions may also result from loss of resources (external) or from “system” errors, that is, failures caused by the interaction of two or more components that performed as designed (internal).

Discussion

This book is the only formal textbook on the subject of resilience in which the concept of disruptions is discussed. The word is used in other sources such as Hollnagel et al (Resilience Engineering: Concepts and Precepts, Ashgate Publishing Ltd, 2006, UK) and various government document. However, no other comprehensive definition has been found.
