Composition of services provides value added\udservice by combining existing services and is essential to meet\udthe varying users’ requests. The need for on-demand, automated,\udon-the fly and failure resilient service composition led to\udvarious dynamic and adaptive service composition approaches.\udAn overview of several existing composition approaches is\udprovided and the limitations in these approaches are identified\udand depicted as research opportunities. It has been found that all\udthese approaches behave in a rigid way to respond to the\udchanging services environment. They are bridged by proposing\uda Goal-Directed Orchestration approach which employs an\udorchestration engine to provide flexibility in responding to the\udchanges in dynamic services environment. To illustrate how our\udapproach could work better than the other existing approaches,\udwe discussed with a usage scenario in travel trip planning\uddomain. Our proposed model is compared with the existing\udmodels based on a set of defined features
