High Integrity Software

High integrity software is required for those systems whose failure as a result of software error would have unacceptable consequences, either because of the loss of assets, or because of the threat to life. The extra reliability required for high-integrity systems is provided by paying particular attention to critical areas of the design, by the use of specialized techniques including software verification, by exerting controls during production and maintenance, by extensive testing and by independent review. The aim of the book is to give practical guidance on the use of existing and developing techniques, some appreciation of relative merits and of how techniques may be used in combination. It also provides surveys of the existing literature. The chapters come from both professional and academic authorities and constitute essential reading for professional software engineers and technical managers in civil and military establishments.
