This Malaysian Standard defines quality in use metrics for the characteristics defined in MS 1883: Part 1, and is intended to be used together with MS 1883: Part 1.
This Malaysian Standard contains:
- an explanation of how to apply software quality metrics;
- a basic set of metrics for each characteristic; and
- an example of how to apply metrics during the software product life cycle.
It includes as informative annexes a quality in use evaluation process and a reporting format.
This Malaysian Standard does not assign ranges of values of these metrics to rated levels or to grades of compliance, because these values are defined for each software product or a part of the software product, by its nature, depending on such factors as category of the software, integrity level and users' needs. Some attributes may have a desirable range of values, which does not depend on specific user needs but depends on generic factors, i.e. human cognitive factors. This Malaysian Standard can be applied to any kind of software for any application. Users of this Malaysian Standard can select or modify and apply metrics and measures from this Malaysian Standard or may define application-specific metrics for their individual application domain. For example, the specific measurement of quality characteristics such as safety or security may be found in International Standards or Technical Reports provided by IEC 65 and ISO/IEC JTC1/SC 27
