Many system models of dependability have been proposed, and this paper is an attempt to provide yet another. Dissatisfaction with existing models arises from the fact that they deal solely with the computer component and ignore the roles played by people in the overall scheme of the system operating in its environment. It is argued that a care- fully defined terminology which covers not only the computational aspects of dependability but also the human rules, roles and relations involved is required in order to clarify the various responsibilities in designing, analysing, and using dependable systems. Such a term- inology is developed in conjunction with a set of models of a communications system, and it is shown how this naturally leads to a taxonomlf of possible weaknesses and an analytical method of system assessment with respect to issues of dependability.
