Measures for Cloud Computing Effectiveness Assessment

Abstract

For the Cloud Computing Effectiveness Assessment Model (CCEAM) that was recently proposed, a set of operationally and objectively defined measures are presented. The model incorporating these measures is validated by case studies carried out in five companies from four different categories of involvement with cloud computing. It is shown in the context of the case studies that CCEAM is applicable for assessing cloud computing strengths and weaknesses of organizations.

Measures for Cloud Computing Effectiveness Assessment

“…For complete findings of the case studies as well as a detailed discussion of specific findings, the reader is referred to (Yarlikas & Bilgen, 2013d).…”

“…The Cloud Computing Effectiveness Assessment Model (CCEAM) that was proposed recently (Yarlikas & Bilgen, 2013b) consists of 42 variables and a total of 142 generic measures categorized in the technical, economical, organizational and external dimensions. The intermediate stages of the qualitative research that led to the final model have been documented in (Yarlikas & Bilgen, 2013a). Findings and interview transcipts of four exploratory case studies carried out in 10 companies to finalize the model are available in (Yarlikas & Bilgen, 2013c).…”

“…The intermediate stages of the qualitative research that led to the final model have been documented in (Yarlikas & Bilgen, 2013a). Findings and interview transcipts of four exploratory case studies carried out in 10 companies to finalize the model are available in (Yarlikas & Bilgen, 2013c). A major shortcoming of the study was that the measures used to evaluate the variables were subjectively defined and interpreted in a case-specific fashion in the exploratory studies.…”

“…In fact as shown in the confirmatory case studies, only the relevant ones for any specific organization have been used for assessment. The method applied to develop and validate these measures is again qualitative, starting from an extensive literature review (Yarlikas & Bilgen, 2013a), continuing with exploratory case studies reported in (Yarlikas & Bilgen, 2013b;Yarlikas & Bilgen, 2013c), and culminating in the application of the derived definitions of all measures in confirmatory case studies. Interviews conducted in the studied organizations have shown that with the present set of measures, CCEAM is applicable and provides a meaningful and useful assessment of the cloud computing effectiveness of firms, whether they are service providers, or clients, or position themselves in an intermediate functionality.…”
