Among the many challenges of engineering dependable, self-managed, component-based systems is their need to make informed decisions about adaptive reconfigurations in response to changing requirements or a changing environment. Such decisions may be made on the basis of non-functional or QoS aspects of reconfiguration in addition to the purely functional properties needed to meet a goal. We present a practical approach for using non-functional information to guide a procedure for assembling, and subsequently modifying, configurations of software components, and compare the performance of two variants of the approach. In addition, we outline a scheme for monitoring non-functional properties in the running system such that more accurate information can be utilised in the next adaptation.
