Support for the development of projects at the level of inventions obtained by resolving technical contradictions in technical systems is limited to disconnected clusters of engineering space and has no unity. The high level of technical solutions found, capable of bringing the basic technical system closer to perfection, did not receive information support at the stage of transition from a conceptual solution to the use of CAD technologies, for some reason. As a result of the work carried out by the authors, the boundaries of the unformalized area between clusters are determined and a model of its filling is constructed, the task of which is to restore the data deficit responsible for the output parameters of the technical system. One of the variants of such models of pre-project research in the engineering space characterized by a significant reduction in the number of parameters of the technical system responsible for achieving output indicators and requirements of CALS technologies is proposed. The scope of the model implementation within the framework of a human-machine interface using data of distinctive features and their parameters distributed in the operational area of a technical system with a pronounced technical difference is proposed.

The basic concepts in the field of software quality testing and evaluation are defined. In particular, the concepts of verification, validation and software lifecycle and their role in the testing process are considered. The concept of an artifact in the software lifecycle is considered. The Russian and international standards in the field of software quality assessment are taken into account. The existing methods of software verification are regarded: expertise, static analysis, formal methods, dynamic and synthetic methods.An overview of software quality assessment methods used in software development and testing cycles is presented. Functional and administrative factors affecting software quality are also considered. The article lists modern testing automation tools that can be used today. The review material of the article will be useful for software developers, novice testers and related specialists.
