Bridging the Front Stage and Back Stage in Service System Design

Abstract: Service management and design has thus far primarily focused on the interactions between employees and customers. This perspective holds that the quality of the "service experience" is determined by the customer during this final "service encounter" that takes place in the "front stage." This emphasis discounts the contribution of the activities in the "back stage" of the service value chain where materials or information needed by the front stage are processed. However, the vast increase in web-driven consumer self-service applications and other automated services requires new thinking about service design and service quality. It is essential to consider the entire network of services that comprise the back and front stages as complementary parts of a "service system." We need new concepts and methods in service design that recognize how back stage information and processes can improve the front stage experience. This paper envisions a methodology for designing service systems that synthesizes (front-stage-oriented) user-centered design techniques with (back-stage) methods for designing information-intensive applications.

Evaluating the scalability of a web service-based distributed e-learning and course management system

Abstract: A growing concern of Web service providers is scalability. An implementation of a Web service may be able at present to support its user base, but how can a provider judge what will happen if that user base grows? We present a modelling approach based on process algebra which allows service providers to investigate how models of Web service execution scale with increasing client population sizes. The method has the benefit of allowing a simple model of the service to be scaled to realistic population sizes without the modeller needing to aggregate or re-model the system.

Processing system for providing services and processing method therefor

Abstract: In a system wherein, a point value is set as a consideration for a service to be offered, a point value to be received as a consideration when a service is given is informed to a service user who desires to receive the service and when the service has been offered, the service provider receives the point value from the service user as the consideration of the service offering, thereby, a service providing system or a processing method of providing services is realized which can provides services more easily to service users.

Method for multi-sourcing technology based services

Abstract: A computer implemented method of assigning responsibility for multi-sourced technology based services, the method including the steps of: defining a plurality of service delivery functions, defining collections of services that are to be provided by several service providers, providing metrics associating the service delivery functions with the collections of services, and inserting the metrics into a model to indicate which service providers are assigned responsibility for the service delivery functions.

Service Composition Techniques Using Data Mining for Ubiquitous Computing Environments

Abstract: Summary When users want to have a suitable application in ubiquitous computing environments, it is necessary to discover and compose primitive services considering context information. However, previous works focused on only service discovery for user queries and lack the consideration of context information such as location, time, network, computing environment, and preference for users. They also do not use the service history information on service composition. Therefore, we present a framework for a service provisioning middleware system that can discover primitive services and compose dynamic complex services according to the context information. We also describe an algorithm of service composition which uses the service history information and an ontology engine with data mining. Finally, we show that our experiments enhance the possibility of provisioning services considering user’s preference and thus provide users with newly composed optimal services.
