Attributes are not defined in the standard, as they vary between different software products. Software product is defined in a es;aol sense: As a result, the notion of user extends to operators as well as to programmers, which are users of components such as software libraries. The standard provides a framework for organizations to define a quality model for a software product.
On doing isk, however, it leaves up to each organization the task of specifying precisely its own model. This may be done, for example, by specifying target values for quality metrics which evaluates the degree of presence of quality attributes.
ISO/IEC Harmonization with ISO/IEC
Quality-in-use metrics are only available when the final product is used in real conditions. Ideally, the internal quality determines the external quality and external quality determines quality in use. This standard stems from the GE model for describing software quality, presented in by McCall et al. Ixo to”security” and “compatibility” were added as main characteristics.
ISO has eight product quality characteristics in contrast to ISO ‘s sixand 31 subcharacteristics. From Wikipedia, the free encyclopedia. ISO standards by standard number.
