With the improvement of cloud computing and its apparent advantages, companies are becoming increasingly interested in adopting cloud computing services as their IT solution. However, whereas some companies can obtain numerous benefits from the cloud, others can only obtain a few. In addition, the conditions of the IT environment vary from company to company; thus, companies may have differing levels of ability in terms of introducing cloud services. Previous research has shown several emerging issues that companies should address before they adopt public cloud services, but the research seldom focuses on the types of capabilities that companies should acquire after applying these services. This study develops a maturity model for public cloud services. Under this model, companies determine their current usage level of public cloud services and the types of capabilities they require to manage the adoption of public cloud services and to obtain more benefits from these services. After reviewing the previous research, we summarize four main capabilities for adopting public cloud services: (1) IT assets, (2) Integration, (3) Reconfiguration and transfer, and (4) Human resources.Our data were collected from web questionnaires. We received 158 responses, and after deleting those without sufficient data, we found 117 that were usable and complete. Then, we used the multinomial logistic regression to test our hypotheses. Drawing on this research, we reached four conclusions: (1) The three important capabilities that influence the support of using public cloud services are IT assets, integration and reconfiguration and transfer. (2) We ranked the importance of these three significant capabilities. (3) Once companies reach a higher usage level for public cloud services, they can obtain a higher benefit. (4) Human-based resources do not have a significant impact on supporting greater usage level of public cloud services. The results of this study can help companies to effectively migrate from their existing IT system to a cloud-based system.參考文獻 Armbrust, M., Fox, A., Griffith, R., Joseph, A.
