document: Where to adapt dynamic service compositions Peer services depend on one another to accomplish their tasks , and their structures may evolve . A service composition may be designed to replace its member services whenever the quality of the composite service fails to meet certain quality-of-service ( QoS ) requirements . Finding services and service invocation endpoints having the greatest impact on the quality are important to guide subsequent service adaptations . This paper proposes a technique that samples the QoS of composite services and continually analyzes them to identify artifacts for service adaptation . The preliminary results show that our technique has the potential to effectively find such artifacts in services .
