Requirements traceability as the basis for designing a functional and logical architecture of a software system

The paper deals with the formation and transformation of stakeholder requirements for the information system throughout the entire life cycle. It is shown how the seamless architecture provides traceability of requirements from the level of the business process, to the functional and logical architectures of systems, to the selection of criteria and identification of microservices. It is shown how maintaining the traceability of requirements in the presence of business, functional and logical architecture models can reduce the cost of planning complex functional and load testing of systems, as well as ensure the interaction of operation, maintenance services and contractors that form the entire system, maintain its integrity during the life cycle.
