MOOC services are revolutionizing from just free offering higher education to professional and intensive courses that learners, employers and society demand. However, there is almost no study about services that such MOOCs provide in domestic papers. So this study tried to analyze the service components of professional programs of MOOCs. For analysis, we adopt the concept of ‘competency.’First, we selected 9 programs from Udacity, edX and Coursera, and classified their services into 10 learning and 10 operating service components. And then we drew MOOC service components according to 3 competencies - foundational competency needed as adult or university students in society, academic competency in higher education, and job competency needed to employees in the workplaces. Finally, we suggested service strategy for MOOC based on competency. These results are expected to be practically applied to various professional and intensive programs of domestic MOOCs.
