We contend that the adaptation of third party services within a composition is an optimisation problem, and that coordination techniques must be used to ensure optimised composite service behaviour. Within the future-computing environment of the mobile user, one will begin to see a convergence between Internet and telecommunication networks, incorporating context information to provide the user with a personalised services environment. As is the nature of the mobile users' environment, nothing can be guaranteed to be static. The dynamic adaptation of services within this environment in response to change is therefore a major factor in the optimal delivery of services to the mobile user. The problem begins when a set of third party services are configured and composed together to deliver a service within this unpredictable environment. We demonstrate our contention through the use of a scenario. We then outline some open issues and future work.
