The article presents proposals for changes to the system of service opinion of soldiers in the Polish Armed Forces. Service/periodic assessment is one of the very important instruments of command and management of military units. The current service/periodic assessment system does not take into account best management practices and requires some changes to improve it and adapt it to the current needs of the Armed Forces. The assessment system should be adapted to the type of organization (company) and take into account its specificity. The proposed interim opinion process adapted a functional approach taking into account its most important aspects. At each stage of the process, the scope of the projects and proposals for changes related to it were indicated. Efforts were made to apply a comprehensive approach involving assessment entities, procedures, coherent tools, specific criteria, assessment methods and techniques, and evaluation principles.
