Cause and Effect in User Interface Development

Abstract

There is a lack of means of translating work products of elicitation to design and using results of evaluation as feedback to design. This paper lays the foundation of a model of evaluation to be built concurrently with the design activity. The evaluation model describes the implications which work models have on design and records the cause/effect relationship between design and the problem domain. The paper presents two case studies from air traffic control that are meant to motivate the need for such an evaluation model and serve as input to its design.
