ISO IEC TR 25060 pdf download Systems and software engineering — Systems and software product Quality Requirements and Evaluation (SQuaRE) — Common Industry Format (CIF) for usability: General framework for usability-related information
This Technical Report describes a potential family of International Standards, named the Common Industry Formats (CIF), that document the specification and evaluation of the usability of interactive systems.
It provides a general overview of the CIF framework and contents, definitions, and the relationship of the framework elements. The intended users of the framework are identified, as well as the situations in which the framework may be applied. The assumptions and constraints of the framework are also enumerated. The framework content includes the following:
⎯ consistent terminology and classification of specification, evaluation and reporting;
⎯ a definition of the type and scope of formats and the high-level structure to be used for documenting required information and the results of evaluation.
This Technical Report is applicable to software and hardware products used for predefined tasks. The information items 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.
This Technical Report focuses on documenting those elements needed for design and development of usable systems, rather than prescribing a specific process. It is intended to be used in conjunction with existing International Standards, including ISO 9241, ISO 20282, ISO/IEC 9126 and the SQuaRE series (ISO/IEC 25000 to ISO/IEC 25099).
This Technical Report does not prescribe any kind of method, life cycle or process.
2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
〈interactive system〉 usability of a product, service, environment or facility by people with the widest range of capabilities
user behaviour that a system accepts as a request for a particular operation
[ISO/IEC TR 11580:2007]
context of use
users, tasks, equipment (hardware, software and materials), and the physical and social environments in which a product is used
interaction between a user and an interactive system as a sequence of user actions (inputs) and system responses (outputs) in order to achieve a goal
accuracy and completeness with which users achieve specified goals
resources expended in relation to the accuracy and completeness with which users achieve goals
〈human-centred〉 structure of an information space and the semantics for accessing required task objects,system objects and other information
NOTE The appropriate combination of organization, labelling, navigation schemes and retrieval mechanisms within an information space will facilitate task completion and efficient access to content.
part of the equipment (hardware, software and materials) for which usability is to be specified or evaluated
freedom from discomfort, and positive attitudes towards the use of the product
