適用范圍：This Technical Report defines quality in use metrics for the characteristics defined in ISO/IEC 9126-1, and isintended to be used together with ISO/IEC 9126-1.This Technical Report contains:? an explanation of how to apply software quality metrics;? a basic set of metrics for each characteristic;? 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 Technical Report does not assign ranges of values of these metrics to rated levels or to grades ofcompliance, because these values are defined for each software product or a part of the software product, byits nature, depending on such factors as category of the software, integrity level and users' needs. Someattributes may have a desirable range of values, which does not depend on specific user needs but dependson generic factors, i.e. human cognitive factors.This Technical Report can be applied to any kind of software for any application. Users of this TechnicalReport can select or modify and apply metrics and measures from this Technical Report or may defineapplication-specific metrics for their individual application domain. For example, the specific measurement ofquality characteristics such as safety or security may be found in International Standards or Technical Reportsprovided by IEC 65 and ISO/IEC JTC1/SC 27.Intended users of this Technical Report include:? Acquirer (an individual or organization that acquires or procures a system, software product or softwareservice from a supplier);? Evaluator (an individual or organization that performs an evaluation. An evaluator may, for example, be atesting laboratory, the quality department of a software development organization, a governmentorganization or user);? Developer (an individual or organization that performs development activities, including requirementsanalysis, design and testing through acceptance during the software life cycle process);? Maintainer (an individual or organization that performs maintenance activities);? Supplier (an individual or organization that enters into a contract with the acquirer for the supply of asystem, software product or software service under the terms of the contract) when validating softwarequality at qualification test;? User (an individual or organization that uses the software product to perform a specific function) whenevaluating quality of software product at acceptance test;? Quality manager (an individual or organization that performs a systematic examination of the softwareproduct or software services) when evaluating software quality as part of quality assurance and qualitycontrol.
