Abstract

The research results of the features of the use of the V-model in the development and evaluation of the quality of software of measuring instruments (MI) were presented. The analysis of the possibility of using a cascade software development strategy and its application to assessing the quality of the software being developed was carried out. It is difficult to implement a classical cascade model in its pure form, therefore, variants of such a model with feedback between its separate stages was developed. The disadvantages and advantages of the V-model, which supports the cascade strategy of one-time execution of software development stages, are considered. The main purpose of the V-model is to provide planning testing software in the early stages of its development. V-model is aimed at simplifying the understanding of the complexity of software development. It is used to determine a single procedure for developing software, hardware and user interface. To reduce the shortcomings of the cascade strategy, a number of modifications of the V-model have been developed due to the type of feedback that provides the ability to modify the results of the previous stages of development. Specific guidelines and recommendations of international and regional organizations for legal metrology have been used to determine the components for quality assessment of MI software. The tasks of developing a MI software on the left side of the letter V begin with the definition of requirements to the MI itself, then to the MI software, and only then as a traditional software development. The V-model of the development and evaluation of the MI software quality is proposed, which allows you to adapt this model to a particular MI at the very beginning of the software development. It takes into account all the specific components of software testing for the MI. The degree of verification of the components of the MI software depends on the risk classes that are assigned to the software, depending on the MI for which it is created. The V-model of development and quality assessment of software of MI which takes into account all the specific components of the test are presented.
