Abstract
When a new policy is adopted, it is not clear in advance which department will be in charge of it. In particular, in the case of policies involving multiple departments, which department will be in charge will be management decision as an organization. In this research, regarding the decision process of policy department, we focus on open data which is considered to be a policy issue related to information and communication policy. We conduct a case analysis on which department in the municipality has been in charge of the open data department. The purpose of this research is to consider how to respond as an organization to newly emerging policy issues.
