The development of evaluation and effective public administration mechanisms are crucial for providing effective e-government services. The paper explores the international expertise in the field of e-service evaluation. The organization and provision of e-services in government entities, as well as the evaluation regarding the organization and functioning of information systems are carried out by “ASAN service” system in Azerbaijan. The assessment of organization and functioning of e-services is conducted by considering three determined criteria: the level of digitalization and relevance, the level of information openness and accessibility, and the level of convenience of use. The evaluation of e-services allows improving the level of services and the development of feedback mechanisms and currently, much attention is attributed to the development of citizen-centered services (pp.76-83).
