Abstract

Technically-based models of dependability such as Laprie's model suggest that there are attributes that should be reflected in the design of a system. These attributes tend to be attributes of the software or hardware and the models assume that system operators can be treated in the same way as software or hardware components. While this approach may be valid for some control systems with tightly specified operational processes, we argue that it must be extended if it is to be applied to systems where there is significant discretion on the part of the user as to how they will use the system. In particular, for systems in the home, we argue that the notion of dependability should tie broadened This paper suggests that through the design of assistive technology (AT) systems for older people we can demonstrate the user should be placed at the centre of the process when considering system dependability.
