Audit of software quality by valuing method

Abstract

A possibility of a software quality estimation becomes a necessity as the software costs gradually increase. Quality measurement methods are being sought in accordance with customer’s and developer’s needs. These methods may contribute to an improvement of the quality of the delivered software product. Quantitative methods are regarded as most useful apart from widely used descriptive ones. A repetitive application of the above methods will allow us to get credible coefficients of validity of quality criteria that are at issue. The existing models of software quality were compared. A need of supplementing the above models with a lacking aspects of quality was noticed in the existing models. A multicriterial model of the software product was proposed because of a collective character of the quality. The process of audit of the software quality was described on the basis of methods applied in an engineering of the quality A method of quantifying the states of criteria and a method of graduating the validity of criteria were also presented. The procedure has been illustrated by means of an example. The selection of proper criteria and attributes as essential difficulties in use of quantitative methods as well as the possibility of executing measurements of these attributes have been included.category of quality, criterion, measure, model, validity
