The purpose of this study is to look back on the changes in the working environment of the Crime Prevention Policy Bureau(CPPB) and identify the problems in the operation of the organization and to find solutions to them. Today, the working environment of the CPPB is changing with increasing public interest in crime prevention and the shift in policy paradigm. As people's interest in crime occurrence and prevention increases, various national policies are being introduced, and as skepticism about Institutional treatment has increased, social treatment focusing on diversification and Community treatment has become more important, and as a result, the role of the CPPB in managing the overall social treatment is becoming more important. Based on these changes, the CPPB is making efforts to operate efficiently, including recruiting manpower and establishing affiliated organizations, but it is difficult to achieve practical efficiency. For this reason, the study points out the inefficiency of the management system due to the expansion of the size of the organization and poor coordination of work due to the imbalance in the position of the head of the agency, and suggests the reorganization of the organization status from the current "Bureau" unit to the "Office" and the establishment of an interim supervisory office for the management and supervision of the efficient affiliated agencies.
