An Approach to Critical Success Factors in Designing Cloud-based Application Solutions

Abstract

Recently, the cloud computing is next Internet technology, many companies have designed a comprehensive cloud--based system to consider functional and nonfunctional requirements. Therefore, this paper conducts a two-stage experiments and analysis. In the first stage, we invite professionals to interview and fill out the questionnaire, and then conduct a reliability analysis through the SPSS tool to validate corrections in the questionnaire. This stage erases unnecessary influence factors to find out the CSFs. Secondly, they calculate the weight ratio and rank the sequence for each of the CSFs through analysis of the AHP for questionnaire. After performing above experiments, it obtains the most important CSFs for each facet: the facet of Input Editing is User Experience; the facet of Processing Feature is Computing Logic; the facet of Output Result is Data Accuracy; the facet of Security and Privacy is Data Privacy; the facet of System Architecture is Accessibility; the facet of System Performance is Reliability. In the final calculation of the overall weights of CSFs across all six facets, the top six ranked CSFs cover Data Accuracy, Reliability, Computing Logic, Robustness, Accessibility, and Data Privacy and Encryption. In the future, the proposed methodology can be applied to innovative Cloud-based applications.
