Value Annotation for Service Model Analysis

Service modeling is a critical step in describing customer requirements and designing service systems. The quality of service models determines the quality of service systems to a great extent. To analyze the service models in a way that would show deficiencies in delivering service values, we propose the idea of "value annotation" by which expected values are labeled on the functional elements of service models, and their implementation degrees are connected with QoS of these functional elements. Value annotation\´s elementary principles, process, and model forms are presented. Then, the preliminary principles of value annotation-based service model analysis are briefly introduced. To complement the above discussion, a small case study from ocean transportation service is applied for demonstration.
