The article describes the technical world evolution tendencies, which require proper software and system engineering approaches used for complex systems creation, for example for aircrafts creation. The substantiation of the importance and relevance of using requirements management discipline in software development is made. The main basics of software and system engineering approaches and discipline are set out. System engineering is a discipline, which integrates and harmonizes all activities around entire area of systems creation. The article contains description of information systems, which have been created in GosNIIAS and now are actively used in internal and external works: requirements management information system, problem reports management information system, technological environment for test methods preparation and test results registration. Requirements management information system contains special predefined documents and template, required by standards DO-178, DO-254, DO-330, ARP4754, State Standards GOST 51904 and GOST 34. Using of requirements management system in GosNIIAS and external enterprises is described. Problem reports management information system registers and supports the lifecycle of problem reports, which appear during the work process. Technological environment for test methods preparation and test results registration supports different activities such as test methods, test cases, test procedures preparation and testing on the integration stand, test results registration and test protocols preparation. Some perspective directions of software and system engineering approaches applying in GosNIIAS are listed.
