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.

Objective Operational Definitons Of Measures

CCEAM consists of 24 technical, 7 organizational, 9 economical and 2 external variables, to be evaluated in terms of 80, 31, 29 and 2 measures, in the four dimensions, respectively. Table 1 presents a list of all variables and their abbreviations. In Tables 2 through 8, the measures to be used for assessing variables are presented, together with their abbreviated denotations to be used in the footprint diagrams. These denotations are constructed to indicate the variable with which each measure is directly associated. E.g. Cla2 in Table 2 indicates the second measure for variable “Cloud Applications” (Cla) in Table 1.
