This document describes information items enabling systematic human-centred design for interactive systems. Some of these information items are elaborated by separate International Standards, named the Common Industry Format (CIF) for usability-related information. This document provides the framework of information items, including definitions and the content for each information item. This document includes the following: the intended users of the information items; consistent terminology; the high-level content structure to be used for documenting each information item. 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, ISO 9241-220 and ISO/IEC JTC 1/SC 7 process standards (e.g. ISO/IEC 15288, ISO/IEC 29148). This document focuses on those information items needed for design, development and evaluation of usable systems, rather than prescribing a specific process. It is intended to be used in conjunction with existing International Standards, including the standards of the ISO 9241 series and the SQuaRE documents (ISO/IEC 25000 to ISO/IEC 25099). This document does not prescribe any kind of method, life cycle or process. NOTE The information items produced by human-centred design activities can be incorporated in design approaches as diverse as object-oriented, waterfall, HFI (human factors integration), agile and rapid development.
