A Dynamically Adaptive System (DAS) adjusts its behaviour autonomously at runtime in order to accommodatechanges in its operating environment, which are anticipated in the system’s requirements specification. Question/Problem In this paper, we argue that Dynamic Adaptive Systems’ requirements specifications are more susceptible to change than thoseof traditional static systems. We propose an extension to i* strategic rationale models to aid in changing a DAS. Principal Ideas/Results By selecting some of the types of tracing proposed for the most complex systems and supporting them for DAS modelling, itbecomes possible to handle change to a DAS’ requirements efficiently, whilst still allowing artefacts to be stored in a RequirementsManagement tool to mitigate additional complexity. Contribution The paper identifies different classes of change that a DAS’ requirements may be subjected to, and illustrates with a casestudy how additional tracing information can support the making of each class of change.
