From defects to failures: a view of dependable computing

Abstract: A unified framework and terminology for the study of computer system dependability is presented. Impairments to dependability are viewed from six abstraction levels. It is argued that all of these levels are useful, in the sense that proven dependability procurement techniques can be applied at each level, and that it is beneficial to have distinct, precisely defined terminology for describing impairments to and procurement strategies for computer system dependability at these levels. The six levels in the pro… Show more

“…Devido à necessidade de se ter ambientes cada dia mais confiáveis, surgiu o conceito de dependabilidade. A dependabilidade de um sistema pode ser entendida como a capacidade de oferecer uma funcionalidade específica, que pode ser justificadamente confiável [Avizienis et al 2004], ou ainda, que o sistema executará ações especificadas ou apresentar resultados específicos de maneira confiável [Parhami 1988]. Esse conceito fez com que a International Organization for Standardization (ISO) elaborasse a regulamentação ISO 9000-4/1993 com as Normas de Gestão da Qualidade e Garantia da Qualidade Parte 4: Guia para a gestão do programa de dependabilidade [ISO 2013].…”
