Trade-off and utility in interactive systems design for safety-critical user interfaces.

In developing interfaces for safety critical systems, designers must identify priorities with respect to the different errors and the different hazards that are associated with the system. How can early models of the evolving design be used to identify those priorities? How can the possible errors be identified and their effects be modelled? How can the severity or impact of those effects be computed? And how should the designers understanding of the impact of an error be reflected in requirements and in the emerging design? This work was conducted in collaboration with Chris Johnson at Glasgow.
