Open Systems Dependability: Dependability Engineering for Ever-Changing Systems
Features
- Describes how to achieve dependability in information systems when faced with the above-mentioned situation
- Discusses the notion of Open Systems Dependability as a property of a system that has the ability to continuously provide optimal services
- Details the DEOS process, an iterative process that does not treat the development of a system and operation on it separately
- Examines how to build consensus among stakeholders on the requirements for a target system
Summary
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.
