We show how we built negotiated descriptions of decisions made by the business, how these descriptions emerged through processes of negotiation and reenement and how we envisaged ways in which work processes would be transformed by our new system. We argue that envisaging the changing context of work is a vital step in the successful integration of decision technology.

The framework offers a generic decomposition of any function into a number of elements that can be considered as primarily performed by the machine, or primarily performed by the human user or operator.

In that panel, a tension was raised between dispassionately providing support to the design of products and services, regardless of the intended use, and the social responsibility of the scientist. Consequently, both personal values and the value that good analysis can bring to design were discussed. The technical challenges of HCI are great. However, it is a reasonable assertion that many members of the HCI community feel a need to do good for the world. But what kind of “good”, and how do we define “the world”? We feel that this implicit motivation has received too little explicit attention with HCI. This workshop will give centre stage to values: both the values that motivate the direction of our work and the value that we seek to deliver.

It is important that human-machine interface (HMI) designers are aware of the relationships between their design decisions, operator errors, and the hazards associated with a system. In this paper, we demonstrate how information from risk analysis can be combined with formal specification of the HMI, to support designers in exploring these relationships. We use the concept of interactor to model the human-machine interface (HMI); together with a concept of impact, which we define informally as: “the effect that an action or sequence of actions has on the safe and successful operation of a system.” We show how interactors can be used as design representations for the HMI at the earliest stages of design, as well as providing a medium by which risk analysts can inform HMI designers about the impact of human-errors. To demonstrate the feasibility of this approach, we consider a simple, gas-fired, electricity generating plant as a case study. Our proposed approach is intended to complement, rather than compete with, existing design and analysis methods for the HMI. The method achieves this by making risk analysis information available in the early stages of HMI design.
