Analysis of Interactive Applications

Before building a model it is necessary to understand clearly what has to be included in such a model. In this chapter we discuss some techniques useful to identify information that is important in modelling interactive applications. For this purpose we consider various techniques (scenarios, use cases, task analysis) that are usually applied in the requirement elicitation and specification phases. They usually provide information that is informally structured. As we will see the three approaches that we consider in this chapter (scenarios, use cases, and task analysis) differ mainly in terms of generality: scenarios are very specific descriptions of an example of use; use cases group sets of uses; task analysis is more general and aims at identifying possible general tasks and their features.
