National bodies that are members

11、 of ISO or IEC participate 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 organi

12、zations, governmental and 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. International Standards are drafted in accordance with the rules given in the ISO/IEC

13、Directives, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % o

14、f the national bodies casting a vote. Attention is drawn to the possibility 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. ISO/IEC 25062 was prepared by Joint Technical Committee

15、 ISO/IEC JTC 1, Information technology, Subcommittee SC 7, Software and system engineering. BS ISO/IEC 25062:2006 v Introduction Usability of software is a key factor in predicting successful deployment of that software. Software manufacturers subject software to usability testing at various stages

16、in a products development; some companies that purchase software also test products for usability before making purchasing decisions. Testing often involves (1) subjects who are representative of the target population of users of the software, (2) representative tasks, and (3) measures of efficiency

17、, effectiveness and subjective satisfaction. When this type of experimental situation exists, the testing is termed summative, i.e., the results can be expressed as statistically meaningful measures of central tendency (e.g. mean or median) and variability (e.g. standard deviation). The Common Indus

18、try Format (CIF) for Usability Test Reports is intended for use by usability professionals to report the results of summative usability testing. The CIF standardizes the types of information that are captured about testing with users. The level of detail allows the same or another organization to re

19、plicate the test procedure. The major variables are user demographics, task descriptions, context of the test, including the equipment used, the environment in which the test is conducted, and the protocol by which the subjects and the test administrator(s) interact, as well as the particular metric

20、s chosen to code the findings of the study. The CIF is intended to replace the proprietary formats employed by companies that perform usability testing, both vendors and purchasers of software. Until now there has been no standard format for reporting usability testing results. Advantages of using a

21、 standardized reporting format include (1) a reduction in training time for usability staff since an individual only needs to learn to use one form regardless of how many companies he works for and (2) enhanced potential for increased communication between vendors and purchasing organizations since

22、readers of CIF-compliant reports will share a common language and expectations. The purpose of this International Standard is to facilitate incorporation of usability as part of the procurement decision-making process for interactive software products so that it is easier to judge whether a product

23、meets usability goals. Examples of decisions include purchasing, upgrading and automating. It provides a common format for human factors engineers and usability professionals in supplier companies to report the methods and results of usability tests to customer organizations. Audience The Common Ind

24、ustry Format (CIF) is meant to be used by usability professionals within supplier organizations to generate reports that can be used by customer organizations in the CIF report. The CIF is also meant to be used by customer organizations to verify that a particular report is CIF-compliant. The Usabil

25、ity Test Report itself is intended for two types of readers: Usability professionals in customer organizations who are evaluating both the technical merit of usability tests and the usability of the products; and Other technical professionals and managers who are using the test results to make busin

26、ess decisions. The CIF may also be used within a single organization if a formal report of a summative usability test needs to be generated. In this case additional material such as a list of detailed findings may be included. The report is in two main sections, an Executive Summary and a main body.

27、 The main body contains the Methods and Results sections and is aimed at the first audience above. These sections (1) describe the test methodology and results in sufficient technical detail to allow replication by another organization if the test is repeated, and (2) support application of test dat

28、a to questions about the products expected costs and benefits. Understanding and interpreting these sections will require technical background in human factors or usability engineering for optimal use. The second audience is directed to the Introduction, which provides summary information for non-us

29、ability professionals and managers. The Introduction may also be of general interest to other computing professionals. Decision makers without usability engineering expertise may find the information in the main body to be useful but should rely on expert interpretation when necessary. Organization

30、Clause 1 describes the scope of this specification and the conformance criteria. Clause 4 provides definitions BS ISO/IEC 25062:2006vi of the terms used throughout the document. Clause 5 is the main description of the specification. Additional Information Annex A provides a checklist that can be use

31、d to ensure inclusion of required and recommended information. A glossary is provided in Annex B to define terminology used in the report format description. A Word template for report production can be found at: http:/www.ncits.org/ref-docs/CIF/CIF_template.dot. A printed version of the template ca

32、n be found in Annex C. An example is provided in Annex D illustrating how the format is used followed by an informative bibliography.

33、cope This International Standard is intended to be used to report the measures obtained from a test of usability as defined in ISO 9241-11: effectiveness, efficiency and satisfaction in a specified context of use. NOTE Metrics for other more-detailed usability requirements can be found in ISO/IEC 91

34、26 parts 2 and 3. This International Standard is intended to be used by: usability professionals within supplier organizations to generate reports that can be used by customer organizations; customer organizations to verify that a particular report conforms to this International Standard; human fact

35、ors or other usability professionals in customer organizations who are evaluating both the technical merit of usability tests and the usability of the products; and other technical professionals and managers in the customer organization who are using the test results to make business decisions about

36、 product suitability and purchase. The Executive Summary and Introduction in 5.2 and 5.3 provide summary information for nonusability professionals and managers. Subclauses 5.4 and 5.5 describe the test methodology and results in technical detail suitable for replication, and also support applicatio

37、n of test data to questions about the products expected costs and benefits. Understanding and interpreting these sections will require technical background in human factors or usability engineering for optimal use. The report format assumes sound practice 1, 2 has been followed in the design and exe

38、cution of the test. Test procedures which produce measures that summarize usability should be used, i.e. the test is summative in nature. Some usability evaluation methods, such as formative tests, are intended to identify problems rather than produce measures; the format is not structured to suppor

39、t the results of such testing methods. 2 Conformance A usability test report conforms to this International Standard if it complies with all the requirements in this International Standard (stated as “shall”). The recommendations (stated as “should”) should be implemented whenever appropriate. This

40、International Standard specifies the minimum information that should be provided. Additional information may be included. For example, if an organization finds that an additional list of findings is useful, the list may be included even though it is not specified as part of a conformant CIF report.

NOTE Efficiency, effectiveness, and satisfaction are defined in ISO/IEC 9126 in a similar way to the definiti

45、ons in ISO/IEC 9241. However, in ISO/IEC 9126 they are defined in terms of the software product where as in ISO/IEC 9241 they are defined in terms of the users view. The term efficiency in this International Standard is equivalent to the term productivity in ISO 9126, as the term efficiency has been

46、 defined with a different meaning in ISO 9126. 4.1 usability the extent to which a product can be used by specified users to achieve specified goals with effectiveness, efficiency and satisfaction in a specified context of use NOTE Quality in use is defined in ISO/IEC 9126 in a similar way to the de

47、finition of usability in ISO/IEC 9241. Quality in use may be influenced by any of the quality characteristics, and is thus broader than the definition of usability in ISO/IEC 9126 that is in terms of understandability, learnability, operability, attractiveness and compliance. 4.2 effectiveness the a

48、ccuracy and completeness with which users achieve specified goals 4.3 efficiency resources expended in relation to the accuracy and completeness with which users achieve goals NOTE Efficiency in the context of usability is related to “productivity” rather than to its meaning in the context of softwa

49、re efficiency. 4.4 satisfaction freedom from discomfort, and positive attitudes towards the use of the product BS ISO/IEC 25062:2006 3 4.5 context of use users, tasks, equipment (hardware, software and materials), and the physical and social environments in which a product is used 4.6 user person who interacts with the product 4.7 user group subset of intended users who are differentiated from other intended users by factors such as
