It is inadequate to just assure the functional requirements. Quality of service (QoS) must also be satisfied. An important challenge for developing efficient Service Oriented Architecture (SOA) is to maintain the QoS attributes because of compositional and dynamical environment of SOA. It is significant to scrutinize how quality attributes are supported by SOA. However, implementation of SOA pr...

Abstract This study develops the theory of risk-averse importance sampling and explains its potential application to forest inventory estimation through use a heuristic simulation. When risk-producing elements landscape are known, strategy can be created that results in fewer samples high-risk areas. Our simulation shows for certain populations, highly effective at reducing both risk field crew...

This paper develops a new explanation for user satisfaction with IS. Combining insights from expectation (dis)confirmation theory (ECT) and importance-performance analysis (IPA), we focus on the gaps between the importance of particular IS attributes, and the performance of a system on those attributes, as an explanation for user satisfaction. We identify 12 relevant system attributes and theor...

The purpose of this study is to examine the relationship between local government services and the overall satisfaction of users with the e–recruitment website (e–job website) in Taiwan. A two–dimensional mean value matrix (TDMVM) technique was used to explore the identification, classification, and application of website service quality. The results show that the asymmetrical relationship betw...

This study proposes perceived ‘Importance-Performance Analysis’ by simultaneously integrating ‘importance-performance analysis’ and Kano’s model in identifying key success factors. Kano’s model, which provides a two-dimensional view of quality, is a very useful tool to identify which customer requirements of a particular product or service might be more than the proportional satisfaction to cus...
