This article highlights in detail the theoretical and practical foundations of assessment based on the rating system in strengthening the sustainability of commercial banks. The article analyzes the international experience of banking supervision, methods of rating assessment, as well as approaches to assessment based on the Camels system. The evaluation criteria, scales and methodological approaches used in rating systems, in particular numerical and alphabetical rating expressions, are considered in detail. The advantages, limitations, and conditions of using complex and expert assessment methods are also substantiated, as well as essential aspects of the assessment model when choosing a criterion. The article highlights the need to collect high-quality information, apply mathematical and statistical models, and choose the right assessment parameters to improve the effectiveness of the rating system. The rating system is recognized as an important tool in improving the reliability and stability of banks through an objective assessment of their financial condition.

The efficiency of public procurement activities of government customers is a key factor in ensuring the rational use of budgetary funds and improving the effectiveness of the public finance system. In the context of the digital transformation of the economy and the increasing complexity of the institutional environment, there is a growing need for a comprehensive evaluation of procurement activities that takes into account not only financial outcomes but also process-related, human resource, and strategic aspects. This article examines theoretical and methodological approaches to assessing the efficiency of public procurement activities of government customers. Based on an analysis of international research, the necessity of moving from narrowly focused financial criteria toward a multidimensional system of indicators integrating economic, process, institutional, and labor-related parameters is substantiated. Particular attention is paid to indicators characterizing operating costs, labor productivity of procurement units, as well as the structure and concentration of suppliers.

The proposed system of indicators makes it possible to identify reserves for improving procurement efficiency, optimize the use of financial and human resources, and enhance the transparency and manageability of procurement processes. The results of the study may be used by government customers in the development of key performance indicators (KPIs), the improvement of monitoring mechanisms, and the formulation of strategies for the development of the public procurement system

This article explores modern methodological approaches to assessing the quality of banking services provided to individuals. In the context of digital banking expansion, omnichannel service models, and the increasing importance of customer experience, traditional evaluation criteria are no longer sufficient. The study conceptualizes service quality as a multidimensional economic category and proposes an integrated assessment framework incorporating functional efficiency, digital interface usability, communicative transparency, security standards, and customer loyalty indicators. Particular emphasis is placed on combining subjective satisfaction metrics with objective operational parameters. As a result, a modern methodological model is developed to support continuous monitoring and strategic management of service quality in retail banking for individuals
