This book describes how to achieve dependability in information systems. The author first proposes viewing systems as open systems instead of closed systems and presents Open Systems Dependability as a property for a system that has the ability to provide optimal services, minimize damage when stoppages occur, resume services quickly, and achieve accountability. He then outlines the DEOS process, an integrative process for achieving the desired dependability in information systems.
