ISO 9241-220-2019 人機交互的人類(lèi)工效學(xué)--第220部分:組織內啟用、執行和評估以人為中心的設計的過(guò)程 Ergonomics of human-system interaction — Part 220: Processes for enabling, executing and assessing human-centred design within organizations

This document describes the processes and specifies the outcomes by which human-centred 
design (HCD) is carried out within organizations. Human-centred design aims to meet requirements for 
human-centred quality (see Annex E) throughout the life cycle of interactive systems. The processes are 
described from the viewpoint of those responsible for the analysis, design and evaluation of the human 
use of interactive systems. The process descriptions include the purpose, benefits, outcomes, typical 
activities and work products for each process, and are for use in the specification, implementation, 
assessment and improvement of the activities used for human-centred design and operation in any 
type of system life cycle. They can also provide the basis for professional development and certification.
The processes are associated with the domains of ergonomics/human factors, human–computer 
interaction, usability and user experience. This document does not include specific methods for human-
centred design, nor does it describe processes for organizational redesign.
The scope of this document does not include other aspects of ergonomics, which include the design of 
organizations as well as systems for human use, and which extend beyond the domain of design; for 
example in the forensic analysis of the causes of accidents and in the generation of data and methods of 
measurement.
NOTE 1 ISO/TS 18152 is a related standard with a broader scope than this document. It includes the 
organizational processes for the identification and handling of issues related to both users and other stakeholders.
The intended application of this document is computer-based interactive systems. While the processes 
apply to interactive systems that deliver services, they do not cover the design of those services. The 
relevant aspects of the processes can also be applied to simple or non-computer–based interactive 
systems.
NOTE 2 Human-centred design concentrates on the human-centred aspects of design and not on other aspects 
of design such as mechanical construction, programming or the basic design of services.
The process descriptions in this document provide the basis for a rigorous assessment of an enterprise’s 
capability to carry out human-centred processes in compliance with the ISO/IEC 33000 family of 
standards.
This document is intended for use by organizations that want to address and improve their treatment 
of human-centred design of either their internal systems or the products and services they provide, and 
the procurement of systems and parts of systems. The processes can be applied by small- and medium-
sized enterprises as well as by large organizations.st edition 2019-03 Ergonomics of human-system interaction — Part 220: Processes for enabling, executing and assessing human-centred design within organizations Ergonomie de l'intéraction homme-système — Partie 220: Processus de validation, d'exécution et d'évaluation de la conception centrée sur l'opérateur humain au sein des organisations Reference number ISO 9241-220:2019(E) ？ ISO 2019 ISO 9241-220: 標準截圖
