Özet:

Organizations have migrated from on-premise enterprise information systems to Cloud-based Enterprise Information Systems (Cloud-EIS) due to the benefits of cloud computing, such as flexibility, availability on demand, and interdependence in information technology infrastructure. Accordingly, enterprises perceive the significance of the quality of Cloud-EIS for improving their businesses, and they pay more attention to selecting the suitable Cloud-EIS. Having looked at the extensive literature, only a few researchers have studied the quality of cloud-based solutions, yet their quality dimensions appear to be subjective, not well-quantifiable, and insufficient for evaluating the quality of Cloud-EIS. While this area is not completely explored, it has attracted deep interest from both enterprises and cloud providers. Therefore, this study presents a comprehensive and hierarchically-structured quality model of Cloud-EIS, which provides a systematic evaluation for diagnosing the quality of Cloud-EIS products. Consequently, the metrics of the quality model of Cloud-EIS are developed and used for quality evaluation of three Cloud-EIS products. Finally, the Analytic Hierarchy Process (AHP) method is employed in order to rank the quality factors of Cloud-EIS. The results show that the most significant quality factors are determined as security & privacy, reliability, functionality, usability and maintainability.
