Abstract

The emergence of new information system (IS) service technologies yields opportunities and challenges in identifying and monitoring quality of services that providers are delivering. Unfortunately, very few approaches have applied accurate and unbiased views on service quality that takes into account the true value of the service provided. This paper poses the definition of quality of service for IS services (QoSIS) and examines how to discover and select high-quality IS services from the viewpoint of the service customers. This will be accomplished through the development of a QoSIS-based service acquisition model by introducing a quality assurance party (QAP) and two quality notions that are respectively referred for traditional customer/provider service and SaaS (software as a service).
