This paper proposes an Authorization-Pull support for Community Authorization Services (CAS), an authorization-push model for the Grid authorization by the Globus Alliance, to evaluate it in the role of a pull model. The proposed system tries to evaluate the advantages and use of an authorization-pull model in the grid scenario making use of CAS and compares the same with the push-model origina...

Co-design has potential to help voluntary organisations deliver better services, since it encourages users to co-create services that will be delivered to them. However, the extent of codesign practice in the voluntary sector is unknown. Thus, our research investigated current state of knowledge of co-design in this sector.

Moving beyond questions about “services” and “the services economy,” this panel considers fresh ways of thinking about service innovation in the era of pervasive digitization. Panelists will argue that our understanding of digital services and products is radically transformed if we consider all exchanges to be service-for-service exchanges in which customers and suppliers co-create value in ex...

Active participation of diverse stakeholders such as consumers or experts in service engineering is critical. It ensures that relevant aspects of service quality, service acceptance and service compliance are addressed. However, coordination of diverse stakeholder inputs is difficult and their collaborative creation of common design artifacts demands novel engineering solutions. We present a se...

Product-related services are of particular interest of companies and should be supported through an appropriate network strategy. However, in the service field, e-business solutions and current standards are still not or only partially considering specifications and related variables of services. We...
