16、Usability of software is a key factor in predicting successful deployment of that software. Software manufacturers subject software to usability testing at various stages in a products development; some companies that purchase software also test products for usability before making purchasing decisi

17、ons. 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, effectiveness and subjective satisfaction. When this type of experimental situation exists, the testing is termed summative, i.

18、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 Industry Format (CIF) for Usability Test Reports is intended for use by usability professionals to report the results of summative usa

19、bility 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 replicate the test procedure. The major variables are user demographics, task descriptions, context of the test, including the equi

20、pment 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 metrics chosen to code the findings of the study. The CIF is intended to replace the proprietary formats employed by companies that per

21、form 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 standardized reporting format include (1) a reduction in training time for usability staff since an individual only needs to lea

22、rn 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 readers of CIF-compliant reports will share a common language and expectations. The purpose of this International Standard is to

23、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 meets usability goals. Examples of decisions include purchasing, upgrading and automating. It provides a common format for human

24、factors engineers and usability professionals in supplier companies to report the methods and results of usability tests to customer organizations. Audience The Common Industry Format (CIF) is meant to be used by usability professionals within supplier organizations to generate reports that can be u

25、sed 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 Usability Test Report itself is intended for two types of readers: Usability professionals in customer organizations who are evaluating

26、 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 business decisions. The CIF may also be used within a single organization if a formal report of a summative usability test needs to be

27、 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. The main body contains the Methods and Results sections and is aimed at the first audience above. These sections (1) describe th

28、e 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 data to questions about the products expected costs and benefits. Understanding and interpreting these sections will require technic

29、al background in human factors or usability engineering for optimal use. The second audience is directed to the Introduction, which provides summary information for non-usability professionals and managers. The Introduction may also be of general interest to other computing professionals. Decision m

30、akers without usability engineering expertise may find the information in the main body to be useful but should rely on expert interpretation when necessary. Organization Clause 1 describes the scope of this specification and the conformance criteria. Clause 4 provides definitions BS ISO/IEC 25062:2

31、006vi 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 used to ensure inclusion of required and recommended information. A glossary is provided in Annex B to define terminology used in th

32、e 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 can be found in Annex C.

BS ISO/IEC 25062:20061Software engineering Software product Quality Requirements and Evaluation (SQuaRE) Common Industry Format (CIF) for usability test reports 1 Scope This International Standard is intended to be used to report the measures obtained from a test of usability as defined in ISO

34、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 9126 parts 2 and 3. This International Standard is intended to be used by: usability professionals within supplier organizations to g

35、enerate reports that can be used by customer organizations; customer organizations to verify that a particular report conforms to this International Standard; human factors or other usability professionals in customer organizations who are evaluating both the technical merit of usability tests and t

36、he 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 product suitability and purchase. The Executive Summary and Introduction in 5.2 and 5.3 provide summary information for nonusabili

37、ty professionals and managers. Subclauses 5.4 and 5.5 describe the test methodology and results in technical detail suitable for replication, and also support application of test data to questions about the products expected costs and benefits. Understanding and interpreting these sections will requ

38、ire 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 execution of the test. Test procedures which produce measures that summarize usability should be used, i.e. the test is summative in n

39、ature. Some usability evaluation methods, such as formative tests, are intended to identify problems rather than produce measures; the format is not structured to support the results of such testing methods. 2 Conformance A usability test report conforms to this International Standard if it complies

40、 with all the requirements in this International Standard (stated as “shall”). The recommendations (stated as “should”) should be implemented whenever appropriate. This International Standard specifies the minimum information that should be provided. Additional information may be included. For examp

41、le, 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.

45、 The source for definitions 4.1 to 4.9 is ISO 9241-11:1998. NOTE Efficiency, effectiveness, and satisfaction are defined in ISO/IEC 9126 in a similar way to the definitions 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 d

46、efined 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 defined with a different meaning in ISO 9126. 4.1 usability the extent to which a product can be used by specified users to achiev

47、e 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 definition of usability in ISO/IEC 9241. Quality in use may be influenced by any of the quality characteristics, and is thus broader

48、than the definition of usability in ISO/IEC 9126 that is in terms of understandability, learnability, operability, attractiveness and compliance. 4.2 effectiveness the accuracy and completeness with which users achieve specified goals 4.3 efficiency resources expended in relation to the accuracy and

49、 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 software efficiency. 4.4 satisfaction freedom from discomfort, and positive attitudes towards the use of the product BS ISO/IEC 25062:200634.5 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 p
