Whenever something is built – be it a bridge, handheld Web browser or a new workflow application – models are likely to be involved. Models are used both to evaluate a design (have we made the right choices?) and in the construction process itself (i.e. helping us to generate designs and other artefacts). Models are important in interactive systems design and evaluation. In this unit you will look models and modelling techniques that focus on users. The unit begins by looking at user requirement modelling and continues by considering two example cognitive models (GOMs and KLM) that are used to capture and evaluate user information processing behaviour.
Why are models important in the design process? Consider what advantages there are to using models.
In what ways do models contribute to the design process?
Answer at the end of the chapter.
Both user centred requirements analysis and cognitive modelling employ models. Consider what the fundamental differences between the two approaches use models.
