Utility-based adaptation approaches permit to determine the "best" suited variant of an application at run-time. Utility policies are usually specified in terms of resources and QoS dimensions. Although utility policies provide a precise formulation for adaptation decision, they are difficult to specify. The developer especially needs assistance in the specification of performance properties. In this paper, we investigate using a performance engineering framework, for the specification of such properties and identify several open research issues. Copyright 2007 ACM.
