The Review of Standardized Risk-Oriented Methods and Models to Ensure the Quality Assurance of the System

The review focuses on the quality assurance process, which is widely used in the design, operation, modernization and development of various types of quality assurance and confirmation systems. Examples are systems created and functioning in the interests of public authorities and corporations, energy, financial and economic, insurance and industrial structures, the fuel and energy complex, the aerospace industry, emergency services, housing and communal services, etc. The quality assurance process under consideration is one of 30 standardized processes in the systems life cycle according to ISO/IEC/IEEE 15288 "Systems and software engineering ‒ System life cycle processes" and GOST R 57193 "System and software engineering. System life cycle processes" (processes of agreement, organizational support of the project, technical management and technical processes are covered). The review describes the very quality assurance process, defines the role of risk-based methods and models. The possibilities of probabilistic risk analysis for the selection of preventive measures to counter threats are presented, the characteristics of quantitative indicators and typical methods and models for predicting risks, as well as tasks for ensuring quality assurance are given. The risk is defined as a combination of the probability of damage and the severity of the damage to the system. The ideas outlined in the review are brought to the level of implementation in GOST R 59994-2022 "System Engineering. System analysis of the quality assurance process for the system".
