Research issues in designing Services for Quality

Designing a Service for Quality should be achieved by a model driven design from business needs level down to implementation level. This paper intends to introduce the key issues that spin around designing Quality of Service (QoS) oriented business services and it describes also a possible set of solutions and guidelines. The main novelties are the integration of performances modelling and functional modelling. This would result in a performance oriented extension of business process notation and execution languages as well as of methodologies for business processes design.
