Continuous adaptive requirements engineering: An architecture for self-adaptive service-based applications

Engineering self-adaptive service-based applications significantly challenges the role of requirements engineering (RE). Such systems need to cope with the evolving requirements at runtime by monitoring the changes in users´ preferences and in the environment, evaluating the changes and enacting a suitable behavior ensuring an acceptable level of quality for their users. This calls for continuous reappraisal of their requirements specification enabling them to reason for them at run-time. Recently, we proposed a novel framework for Continuous Adaptive RE (CARE) supporting self-adaptive service-based applications and on conceptual tools needed to realize RE at run-time. In this position paper, we focus on a conceptual architecture for the CARE framework, and illustrate how it can work using scenarios from travel domain. Potential impact of our work and useful integration with recent studies are discussed, highlighting open points for future research.
