12、066:2016ISO/IEC 25066:2016(E)ForewordISO (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of Internatio

13、nal 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 and non-governmental, in liaison with

14、 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 the ISO/IEC Directives, Part 1. In pa

15、rticular 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 possibility that some of the elements of this

Usability can be a

20、chieved by applying human-centred design throughout the lifecycle. In order to enable a human-centred approach to be adopted, it is important that all the relevant types of information related to usability (information items) are identified and communicated. The identification and communication of r

21、elevant types of information related to usability enables the design and testing of the usability of a system.This International Standard provides a framework and consistent terminology for reporting the evaluation of an interactive system. It is intended to assist usability specialists and develope

22、rs in documenting and communicating usability-related information as part of the system development lifecycle.The Common Industry Format (CIF) for Usability family of International Standards is described in ISO/IEC TR 25060 and is part of the SQuaRE (Systems and software Quality Requirements and Eva

23、luation) series of standards on systems and software product quality requirements and evaluation (ISO/IEC 250001), ISO/IEC 25001, ISO/IEC 250212), ISO/IEC 250233), ISO/IEC 25040, ISO/IEC 25041 and ISO/IEC 25051).The CIF family of standards uses definitions that are consistent with the ISO 9241 serie

24、s of standards (Ergonomics of human-system interaction), as this is the terminology that is normally used for this subject matter. In some cases, these definitions differ from those in ISO/IEC 25000.CIF standards are published or planned for the following information items: Common Industry Format (C

25、IF) for usability test reports (ISO/IEC 25062);NOTE ISO/IEC 25062 provides more detail for the content of a user observation report for performance measurement. Context of use description (ISO/IEC 25063); User needs report (ISO/IEC 25064); User requirements specification (ISO/IEC 25065); Evaluation

26、reports (ISO/IEC 25066); User interaction specification (planned); User interface specification (planned); Field data report (planned).The CIF standards are part of the “Extension Division” of the ISO/IEC 25000 SQuaRE series of International Standards.

33、t activity involves Context of Use. Human-centred design relies on user needs that are first identified during of the Context of Use analysis. User needs are documented in the User needs report (ISO/IEC 25064), which is an intermediate deliverable that links the Context of Use Description (ISO/IEC 2

34、5063) that contains information about the users, their tasks and the organizational and physical environment, to the user requirements. These items are developed during the Stakeholders requirements definition process described in ISO/IEC 15288.The second activity involves Derived Requirements. The

35、User requirements specification (ISO/IEC 25065) provides the basis for design and evaluation of interactive systems to meet the user needs. User requirements are developed in conjunction with and from part of the overall requirements specification of an interactive system.The third activity involves

36、 Designed Solutions. The “Produce design solutions” activity focuses on designing user interaction that meets user requirements. This activity takes place during the Architectural Design, Implementation, and Integration processes described in ISO/IEC 15288 and produces the information items “User in

37、teraction specification” and the “User interface specification”.The fourth activity involves Evaluation Results. The “Evaluate” activity starts at the earliest stages in the project, evaluating design concepts to obtain a better understanding of the user needs. Design solutions can be evaluated mult

38、iple times as the interactive system is being developed and can produce various types of evaluation reports and usability data such as that described in ISO/IEC 25062. These evaluations can support the ISO/IEC 15288 Validation Process that confirms that the system complies with the stakeholders requ

39、irements.

40、on Industry Format (CIF) for reporting usability evaluations. It provides a classification of evaluation approaches and the specifications for the content items (content elements) to be included in an evaluation report based on the selected evaluation approach(es). The intended users of the usabilit

41、y evaluation reports are identified, as well as the situations in which the usability evaluation report can be applied.The usability evaluation reports in this International Standard are applicable to software and hardware systems, products or services used for predefined tasks (excluding generic pr

42、oducts, such as a display screen or a keyboard). The content elements are intended to be used as part of system-level documentation resulting from development processes such as those in ISO 9241-210 and ISO/IEC JTC 1/SC 7 process standards.The content elements for documenting evaluations can be inte

43、grated in any type of process model.NOTE For the purpose of establishing process models, ISO/IEC TR 24774 and ISO/IEC 33020 specify the format and conformance requirements for process models, respectively. In addition, ISO/IEC 15289 defines the types and content of information items developed and us

44、ed in process models for system and software lifecycle management. ISO/IEC 15504-5 and ISO/IEC 15504-6 (to be replaced by ISO/IEC 33060) define work products, including information items, for the purpose of process capability assessment. Process models and associated information items for human-cent

45、red design of interactive systems are contained in ISO/TR 18529 and ISO/TS 18152.2 ConformanceAn evaluation report conforms to this International Standard if it contains all the required content elements in Clause 5 that are applicable to the type(s) of evaluation, including: additional optional con

46、tent elements that were selected to be part of the evaluation; the content elements for the conformity assessment (if used).3 Terms and definitionsFor the purposes of this document, the following terms and definitions apply.NOTE The CIF family of standards uses definitions that are consistent with t

47、he ISO 9241 series of standards, as this is the terminology that is normally used for this subject matter.
