System aspects of the implementation of experiments to improve the reliability of software and information technologies

The article discusses the system aspects of the implementation of experiments to improve the reliability of software and information technologies. As research methods, system analysis, prototyping of software and information technologies, analysis of business processes, multiversion methodology for developing software tools for information and control systems are used. It is shown that at present, based on open computer networks, it is possible to build reliable systems from universal components. It is noted that the software and information technologies of corporate integrated structures, organized according to this principle, must have an adequate level of fault tolerance within the allocated budgets. Therefore, system experiments in software development are becoming more common in the implementation of such software and information technologies. The basic system aspects and factors that developers and experimenters should take into account when conducting experiments with research prototypes are formulated
