To our knowledge, there is a need to develop a methodological approach to the assessment of united communiti es` human resources` level of interacti ons, as a large group, and of separate structural unit's-a small group. This allows us to determine the dependence of the level of interacti ons on the number of people who interact within a parti cular structure and the nature of the acti vity they carry out-intellectual or manual labor. The purpose of our research is to develop a methodological approach to the assessment of the level of human resources` interacti ons, which allows us to identi fy key areas and policy measures. Expert assessments and analyti cal dependencies are used as research tools in the arti cle. These tools allow us to quanti tati vely determine the level of human resources` interacti ons for an individual enti ty. Empirical implementati on of the proposed approach, using the example of two enti ti es varying in size and nature of labor, allowed us to make a comparati ve analysis and to disti nguish the characteristi c features that are the basis for making managerial decisions. A manager acts as an expert who assesses the presence or absence of a parti cular event in the subordinate unit. The indicator, which characterizes the presence or absence of certain acti viti es and the level of parti cipati on in them, is defi ned on the basis of managerial assessment. The next stage is to determine the interacti on rate by means of certain mathemati cal dependencies and results` analysis. As a result of the research, we got the assessment of the level of human resources` interacti ons between two enti ti es-a united community and a structural unit. The assessment revealed a dependence on the level of interacti ons on the enti ty`s size (small and large groups) and the nature of labor. The results showed that a structural unit, focused on intellectual labor and presented by a small group, has a greater level of interacti ons than a united community, which has a bigger size and a predominance of manual labor.
