National bodies that are members of ISO or IEC participa

15、te in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental an

16、d non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. The procedures used to develop this document and those intended for its further maintenance are described in t

17、he ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of document should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn to the possibil

18、ity that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights.

This first e

21、dition of ISO/IEC 25022, which is a part of the SQuaRE series of standards, cancels and replaces ISO/IEC 9126-4 :2004, with the following changes: measures are given for the revised quality model for quality in use in ISO/IEC 25010; measures are categorized as generally applicable, could be used in

22、a wide range of situations, or specialized for specific needs; annexes that were common to ISO/IEC 9126-2, ISO/IEC 9126-3, and ISO/IEC 9126-4 have been removed (and might be included in a future revision of ISO/IEC 25020).

It provides a set of measures for the ch

25、aracteristics of quality in use (defined in ISO/IEC 25010) that can be used for specifying quality in use requirements (in conjunction with ISO/IEC 25030) and measuring and evaluating quality in use (in conjunction with ISO/IEC 25040 and ISO/IEC 25041). The quality measures included in this Internat

26、ional Standard were selected based on their practical value. They are based on established practice (including, for example, Reference 17). They are not intended to be exhaustive, and users of this International Standard are encouraged to refine them, if necessary. Quality Measurement Division This

27、International Standard is a part of ISO/IEC 2502n Quality Measurement Division of SQuaRE series that currently consists of the following International Standards: ISO/IEC 25020 Measurement reference model and guide: provides a reference model and guide for measuring the quality characteristics define

28、d in ISO/IEC 2501n Quality Model Division; ISO/IEC 25021 Quality measure elements: provides a format for specifying Quality Measure Elements and some examples of QMEs that can be used to construct software quality measures; ISO/IEC 25022 Measurement of quality in use: provides measures, including as

29、sociated measurement functions for the quality characteristics in the quality in use model; ISO/IEC 25023 Measurement of system and software product quality: provides measures, including associated measurement functions and QMEs for the quality characteristics in the product quality model; ISO/IEC 2

30、5024 Measurement of data quality: provides measures, including associated measurement functions and QMEs for the quality characteristics in the data quality model.

This In

33、ternational Standard provides a suggested set of quality in use measures to be used with the quality in use model in ISO/IEC 25010. They are not intended to be an exhaustive set. It includes as informative annexes examples of how to measure context coverage (Annex A), options for normalising quality

34、 in use measures (Annex B), use of ISO/IEC 25022 for measuring usability in ISO 9241-11 (Annex C), a quality in use evaluation process (Annex D), the relationship between different quality models (Annex E), and quality measurement concepts (Annex F). The measures are applicable to the use of any hum

35、an-computer system, including both computer systems in use and software products that form part of the system. This International Standard does not assign ranges of values of the measures to rated levels or to grades of compliance because these values are defined for each system or product depending

36、, on the context of use and users needs. Some attributes could have a desirable range of values, which does not depend on specific user needs but depends on generic factors, for example, human cognitive factors. The proposed quality in use measures are primarily intended to be used for quality assur

37、ance and management of systems and software products based on their effects when actually used. The main users of the measurement results are people managing development, acquisition, evaluation, or maintenance of software and systems. The main users of this International Standard are people carryin

38、g out specification and evaluation activities as part of the following: development: including requirements analysis, design, and testing through acceptance during the life cycle process; quality management: systematic examination of the product or computer system, for example, when evaluating quali

39、ty in use as part of quality assurance and quality control; supply: a contract with the acquirer for the supply of a system, software product, or software service under the terms of a contract, for example, when validating quality at qualification test; acquisition: including product selection and a

40、cceptance testing, when acquiring or procuring a system, software product, or software service from a supplier; maintenance: improvement of the product based on quality in use measures.

41、 specification or quality evaluation that conforms to this International Standard shall: a) select the quality in use characteristics and/or subcharacteristics to be specified or evaluated as defined in ISO/IEC 25010; b) for each selected characteristic or subcharacteristic, all the General (G) qual

42、ity measures defined in Clause 8 should be used. If any are excluded, then provide a rationale; c) select any Special (S) quality measures that are relevant; d) if any quality measure is modified, provide the rationale for any changes; e) define any additional quality measures to be used that are no

43、t included in this International Standard; f) define precisely how each quality measure is operationalized (for example details of the measurement method or questionnaire used).
