“…The use of accessible formalisms has long been recognized as a key point to achieve a greater adoption of formal techniques in practice (Heitmeyer, 1998;Bowen et al, 2005). In this regard, many authors have remarked the utility of using scenarios to capture interactions in industrial development settings (see for example Dittmar et al, 2004;Rosson and Carroll, 2003). Likewise, temporal logic is highly suitable to express possible sequences of actions, dependencies between the actions of different actors, etc.…”

“…The latter could check applications or designs against principles of usability engineering rather than software engineering, as soon as the status of development allows the utilization of the evaluation technique. For instance, as soon as the behaviour specification of an interactive application is completed for a particular work task (typically at design time), the ProcessLens technique and tool (Heftberger and Stary, 2004;Dittmar et al, 2004) allows testing the user interface, whether it is complete with respect to task support (Stary, 2006). In addition, any user interface derived from task specifications can be tested with respect to its look and feel at design time, both at the specification level, and as a prototype generated from those specifications.…”

For the automated evaluation of interactive software systems a variety of techniques exists. Different backgrounds, various concepts for representation and processing make it difficult for developers (and users) to identify the proper technique for automated evaluation with respect to acknowledged usability principles, such as the suitability for the task. In order to facilitate the selection and application of automated usability-evaluation techniques, we introduce a template for structured documentation and reflection. Enriching traditional schemes it addresses the relationship between usability principles and parameters used for processing. We consider the relation of usability principles to processing schemes to be of major importance, since it not only facilitates the communication between users and designers, but also reveals ways how qualitative attributes can be mapped on to operational structures. If we could utilize that information for design, e.g., for automatically checking specifications or prototypes, interactive-system development could be improved significantly. The proposed template stems from our work in the EU COST action 294 MAUSE (www.cost294.org) targeting towards quality assessment of usability-evaluation methods.

Abstract. This paper argues for a transfer of knowledge and experience gained in task-based design to Software Engineering. A transformation of task models into activity diagrams as part of UML is proposed. By using familiar notations, software engineers might be encouraged to accept task modelling and to pay more attention to users and their tasks. Generally, different presentations of a model can help to increase its acceptance by various stakeholders. The presented approach allows both the visualization of task models as activity diagrams as well as task modelling with activity diagrams. Corresponding tool support is presented which includes the animation of task models. The tool itself was developed in a model-based way.
