In this paper, we present an approach that supportsefficient quality impact analyses in the context ofiteratively constructed architectures. Since the numberof established architectural strategies and the number ofinter-related models heavily increase during iterativearchitecture construction, the impact analysis of newlyintroduced quality strategies during later stagesbecomes highly effort-intensive and error-prone. Withour approach we mitigate the effort needed for suchquality impact analyses by enabling efficient separationof concerns. For achieving efficiency, we developed anaspect-oriented approach that enables the automaticweaving of quality strategies into architectural artifacts.By doing so, we are able to conduct selective qualityimpact evaluations with significantly reduced effort.
