Abstract

Assurance of software systems has traditionally beensought through the rigour of the development process.The higher the assurance the more demanding thedevelopment process, the highest assurance requiring theuse of formal methods during development. Thisapproach has been followed for decades with somesuccess, but increased assurance brings adisproportionate increase in cost and risk. In this paper achange in emphasis is suggested from the development ofa system to its acceptance. The benefits for highassurance systems are illustrated through a case studyand preliminary experience of high assurance techniquesare reported.
