The purpose of this study is to develop a new model of business processes for the provision of public services on the example of the registration service of the applicant as a person looking for a job at the Center for Employment of Almaty. The subject of the study was selected business processes for the provision of public services  registration of the applicant as a "job seeker". To solve the set tasks, methods of a systematic approach to the study of organizational and economic phenomena, modeling, cost analysis, expert assessments, comparisons, etc. were used. The article builds models of business processes “As-Is” and “To-Be”, identifies duplicate operations, processes were reengineered and the two models were compared using functional cost analysis. Reengineering was carried out not only with the aim of optimizing the business processes of the state authority in question, but also with the goal of developing an “open government”. The article proposes restructuring procedures based on determining priority business processes for reengineering, which, unlike traditional approaches, are ranked based on selected criteria: performance, cost, time, quality, and decomposition by pairwise comparisons; A new model of business processes for the provision of public services has been proposed, a distinctive feature of which is the use of the state portal. As a result of the optimization of business processes, it was possible to reduce the number of operations from twenty-three to five operations, with a decrease in the total duration of the service and its cost. In this state institution, in addition to the considered service for the registration of a citizen as a job seeker, several state services are provided. Thus, it seems appropriate to work on optimizing business processes for other types of services. The results obtained during the study can be used in public institutions of any legal form.
