Systems and software engineering — Systems and software Quality Requirements and Evaluation (SQuaRE) — Common Industry Format (CIF) for reporting usability evaluations
This document 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 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 document are applicable to software and hardware systems and 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 9241-210 and the ISO/IEC JTC 1/SC 7 process standards (e.g. ISO/IEC/IEEE 15288 on systems lifecycle management, ISO/IEC/IEEE 12207 on software lifecycle management and ISO/IEC 33001 on process capability assessment).

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO 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).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

This document was prepared by Technical Committee ISO/TC 159, Ergonomics, Subcommittee SC 4,
Ergonomics of human-system interaction.
This first edition of ISO 25062 cancels and replaces the first edition ISO/IEC 25062:2006, which has been
technically revised.
The main change is as follows:
— the scope of the document has been significantly expanded to go beyond usability test reports and deal
with all types of usability evaluations.
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
This document provides a framework and consistent terminology for reporting the results of usability
evaluations of an interactive system. It is intended to assist those who perform usability evaluations in
documenting and communicating the results of usability evaluations as part of the system development
lifecycle.
NOTE ISO/IEC 25040 specifies a framework for quality evaluation.
The human-centred design approach of ISO 9241-210 is well established and focuses specifically on
making systems usable. Usability can be achieved by applying human-centred design throughout
the system development lifecycle. It is important that all the relevant types of information related to
usability (information items) are identified and communicated as part of a human-centred approach. The
identification and communication of relevant types of information related to usability enables the design
and testing of the usability of a system.
The information items for reporting the results of usability evaluations of an interactive system can be
integrated in any process models. For the purpose of establishing process models, ISO/IEC/IEEE 24774
and ISO/IEC TS 33061 specify the format and conformity requirements for process models, respectively.
In addition, ISO/IEC/IEEE 15289 defines the types and content of information items developed and used in
process models for system and software life cycle management. ISO/IEC TS 33060 and ISO/IEC TS 33061
define work products, including information items, for the purpose of process capability assessment. Process
models and associated information items for human-centred design of interactive systems are contained in
ISO 9241-210 and ISO TS 18152, respectively.
The common industry format (CIF) for usability documents are part of the SQuaRE (Systems and software
Quality Requirements and Evaluation) group of standards developed by ISO/TC 159, and described
in ISO/IEC 25000, Systems and software engineering — Systems and software Quality Requirements and
Evaluation (SQuaRE) — Guide to SQuaRE.
The CIF documents use definitions that are consistent with the ISO 9241 series on ergonomics of human-
system interaction, as this is the terminology that is normally used for this subject matter.
ISO TR 25060 gives an overview of the CIF standards, which include documents covering the following
information items:
— reporting usability evaluations (ISO 25062);
— context of use description (ISO/IEC 25063);
— user needs report (ISO/IEC 25064);
— user requirements specification (ISO 25065).
