Deriving Adaptive Behaviour from i* models

Dynamically Adaptive Systems (DASs) adjust their behaviour at runtime to tolerate changes in context. With potentially incomplete or inaccurate knowledge of an operating environment, tailoring specific behavioural adjustments to individual contextual changes is a time-consuming and errorprone process. i* models of a DAS' behavioural adjustments can aid understanding, and can form part of the specification of the DAS' adaptive behaviour; speeding the specification process. This paper presents an approach by which a DAS' adaptive behaviour may be derived directly from a set of i* models, and a tool capable of performing the derivation automatically.
