In complex service-oriented systems, a number of layers of abstraction may be considered, in particular the models of the organisations involved, how interactions are coordinated and the services which are used and made available, are all relevant to the construction of complex service-oriented systems. As each of these layers is built upon another there is a clear need to provide a maintenance mechanism, capable of maintaining consistency across the concepts used in each layer. In addition, over time designs may change because of the introduction of new requirements and the availability and capabilities of services may change due to implementation modifications or service failures, leading to the need to consider a two-way adaptation, namely between the system design and its run-time. The contribution of this paper is the description of our (novel) mutual adaptation mechanism and, using an industry scenario based on the proposed ALIVE framework, its illustration in use of the kinds of adaptation.
