Since the publication of the first edition in 2002, interest in crisis management has been fuelled by a number of events, including 9/11. The first edition of this text was praised for its rigorous yet logical approach, and this is continued in the second edition, which provides a well-researched, theoretically robust approach to the topic combined with empirical research in continuity management. New chapters are included on digital resilience and principles of risk management for business continuity. All chapters are revised and updated with particular attention being paid to the impact on smaller companies. New cases include: South Africa Bank, Lego, Morgan Stanley Dean Witter; small companies impacted by 9/11; and the New York City power outage of August 2003.
