20、nd focuses specifically on making systems usable. Usability can be achieved 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 id

21、entified and communicated. The identification and communication of relevant 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 interactiv

22、e system. It is intended to assist usability specialists and developers 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

23、 part of the SQuaRE (Systems and software Quality Requirements and Evaluation) series of standards on systems and software product quality requirements and evaluation (ISO/IEC 25000 1) , ISO/IEC 25001, ISO/IEC 25021 2) , ISO/IEC 25023 3) , ISO/IEC 25040, ISO/IEC 25041 and ISO/IEC 25051). The CIF fam

24、ily of standards uses definitions that are consistent with the ISO 9241 series 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 publi

The following discussion also serves as alternative text for

31、the figure. The figure depicts the activities as a set of intersecting circles. The circles overlap to represent that the activities are not separate, but rather overlapping in time and scope, and the outcome of each activity provides the input to one or more other activities. As each human-centred

32、design activity can provide input to any other, no starting point, end point, or linear process is intended. 4) Withdrawn.

33、vities represented as overlapping circles in the diagram where User Needs are at the centre. The first 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/

34、IEC 25064), which is an intermediate deliverable that links the Context of Use Description (ISO/IEC 25063) 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

35、definition process described in ISO/IEC 15288. The second activity involves Derived Requirements. The 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 fr

36、om part of the overall requirements specification of an interactive system. The third activity involves Designed Solutions. The “Produce design solutions” activity focuses on designing user interaction that meets user requirements. This activity takes place during the Architectural Design, Implement

37、ation, and Integration processes described in ISO/IEC 15288 and produces the information items “User interaction specification” and the “User interface specification”. The fourth activity involves Evaluation Results. The “Evaluate” activity starts at the earliest stages in the project, evaluating de

38、sign concepts to obtain a better understanding of the user needs. Design solutions can be evaluated multiple 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 suppor

39、t the ISO/IEC 15288 Validation Process that confirms that the system complies with the stakeholders requirements.

40、dustry Format (CIF) for Usability Evaluation Report 1 Scope This International Standard describes the Common 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

41、 in an evaluation report based on the selected evaluation approach(es). The intended users of the usability 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 applic

42、able to software and hardware systems, products or services used for predefined tasks (excluding generic products, 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 92

43、41-210 and ISO/IEC JTC 1/SC 7 process standards. The content elements for documenting evaluations can be integrated 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

44、, respectively. In addition, ISO/IEC 15289 defines the types and content of information items developed and used 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, fo

45、r the purpose of process capability assessment. Process models and associated information items for human-centred design of interactive systems are contained in ISO/TR 18529 and ISO/TS 18152. 2 Conformance An evaluation report conforms to this International Standard if it contains all the required c

46、ontent elements in Clause 5 that are applicable to the type(s) of evaluation, including: additional optional content elements that were selected to be part of the evaluation; the content elements for the conformity assessment (if used). 3 T erms a nd definiti ons For the purposes of this document, t

NOTE The CIF family of standards uses definitions that are consistent with the ISO 9241 series of standards, as this is the terminology that is normally used for this subject matter.
