Description
Summary:A fundamental demand for IT service providers is to obtain design skills for non-functional requirements (NFRs) of a target IT enabled service system. The design task should identify a number of NFR determinants, such as the architecture of the IT infrastructure, the operational procedure, and the human resources for service delivery. The satisfaction of NFRs has not been validated after implementation or deployment of the service, which causes extensive redesign work. Thus, a modeling method to bridge NFR and IT service design for reducing such risks is introduced, and an NFR evaluation model is provided. Consequently, IT service designers can validate NFRs in the early development phase.
