Abstract
This study stem from a hypothesis that a fundamental reason why SMEs don't use cloud services is the lack of attractive or beneficial services. We found each SaaS provider don't have enough ability to provide adequate services by questionnaires. Then we created ‘Kansai Cloud Plan' to solve this situation, and we verified the validity of this plan and the solution for technical issues by holding a vendors' session twice. Through these discussions we also could create a methodology for a cloud mash-up.
