Abstract: | Requirements engineering (RE) research often ignores or presumes a uniform nature of the context in which the system operates.
This assumption is no longer valid in emerging computing paradigms, such as ambient, pervasive and ubiquitous computing, where
it is essential to monitor and adapt to an inherently varying context. Besides influencing the software, context may influence
stakeholders’ goals and their choices to meet them. In this paper, we propose a goal-oriented RE modeling and reasoning framework
for systems operating in varying contexts. We introduce contextual goal models to relate goals and contexts; context analysis to refine contexts and identify ways to verify them; reasoning techniques to derive requirements reflecting the context and
users priorities at runtime; and finally, design time reasoning techniques to derive requirements for a system to be developed
at minimum cost and valid in all considered contexts. We illustrate and evaluate our approach through a case study about a
museum-guide mobile information system. |
