In Service-Oriented Architecture (SOA), actual quality of service (QoS) is not known until the service is executed since the internals of the service are hidden to service consumers. Hence, quality management of services before publishing is important in SOA environment. To ensure that a qualified service is published, defining metrics for evaluating the QoS is a prerequisite. Therefore, this paper proposes a set of QoS metrics for service providers especially considering the consumer's concern. We first identify unique features of SOA and define quality attributes and metrics. To show the applicability and usefulness of the QoS metrics, we perform a case study for Hotel Reservation Service.
