A correlated uniqueness model of service quality measurement among users of cloud-based service platforms
This research furthers understanding of whether consumers of cloud-based service platforms can distinguish between gap theory dimensions (i.e., expectation and performance) on these platforms. We build upon and extend the work of (Natesan and Aerts, 2016) by applying confirmatory factor analysis on gap scores from survey data to develop and test an improved approach of measuring service system quality in cloud-based service platforms. Using the IS-adapted SERVQUAL instrument, we apply the correlated uniqueness model, which is part of the multitrait-multimethod (MTMM) framework, to evaluate the validity of using GAP scores and account for the effect of the method. There is significant support for method effects as shown by our suggested model paths in the trait convergent validity model with medium-large factor coefficients. Additionally, the fit of the correlated uniqueness model indicates respondents can distinguish between the gap theory dimensions of the IS-adapted SERVQUAL instrument. The praxis of service quality measurement could benefit by using our measurement approach of incorporating error correlations
Social-software-based support for enterprise architecture management processes
Modern enterprises reshape and transform continuously by a multitude of management processes with different perspectives. They range from business process management to IT service management and the management of the information systems. Enterprise Architecture (EA) management seeks to provide such a perspective and to align the diverse management perspectives. Therefore, EA management cannot rely on hierarchic - in a tayloristic manner designed - management processes to achieve and promote this alignment. It, conversely, has to apply bottom-up, information-centered coordination mechanisms to ensure that different management processes are aligned with each other and enterprise strategy. Social software provides such a bottom-up mechanism for providing support within EAM-processes. Consequently, challenges of EA management processes are investigated, and contributions of social software presented. A cockpit provides interactive functions and visualization methods to cope with this complexity and enable the practical use of social software in enterprise architecture management processes
