For increasing the efficiency of solving applied and practical tasks related to transformation of the systems of legislative regulation and law enforcement in the conditions of digitalization, the authors propose using the methodology of scenario analysis that allows the possibility of information support and quality assessment of preparing and making decisions within the framework of managing the indicated processes. The utmost efficiency of using scenario techniques is reached in the process of preparation and assessment of the outcome of strategic solutions as it allows analyzing the alternative options in development of the situation within society and the state in the conditions of imperfect information and uncertainty. In solving tactical problems related to ensuring social stability, it seems reasonable to implement the aforementioned techniques in the process of preparation and assessment of the effectiveness of preventative and prompt measures of counteracting emerging threats.
