and scenario evolution, in which concepts in the abstraction domain and scenarios in the detail domain iteratively evolve. This framework provides another facet of scenario-based requirements analysis. The chapter also illustrates an example of the scenario-based requirements process. The concept of Familyware--communication tools that provide status information about remotely located family members using peripheral displays and devices--is developed through an example process. This example illustrates where scenarios are obtained from and how they evolve. The chapter concludes with a discussion about the characteristics of the scenario-based approach and task analysis.
