ISO 9241-220:2019

Overview

ISO 9241-220:2019 - Ergonomics of human‑system interaction - Part 220 - defines processes for enabling, executing and assessing human‑centred design (HCD) within organizations. The standard specifies the purpose, expected outcomes, typical activities and work products for HCD processes across the lifecycle of interactive systems. It focuses on achieving human‑centred quality (usability, accessibility, user experience and avoidance of harm) for computer‑based and other interactive systems, and is intended for use in specification, implementation, assessment and continuous improvement of HCD capability.

Key topics and technical requirements

• HCD process model: a structured set of processes described from the viewpoint of those responsible for analysing, designing and evaluating human use of interactive systems.
• Process descriptions (Clause 9): purpose, benefits, outcomes, activities and work products - users are allowed to reproduce these process descriptions for assessments.
• Enterprise and project levels:
  • Ensure enterprise focus on human‑centred quality (governance, strategy).
  • Enable HCD across projects and systems (resources, authorization, integration).
  • Execute HCD within projects (planning, context of use, user requirements, design solutions, user‑centred evaluation).
  • Introduction, operation and end‑of‑life considerations for systems.
• Work products and tailoring: guidance on typical artefacts and how to adapt processes to project scale and context.
• Risk and quality aspects: links to risk management and human‑centred quality (Annexes E and F).
• Conformance and assessment: process descriptions provide a basis for rigorous capability assessment (compatible with ISO/IEC 33000 family).

Practical applications and who should use this standard

ISO 9241-220 is practical for organizations that design, procure or operate interactive systems and want to institutionalize effective HCD practices. Typical uses:

• Implementing HCD in software and system development lifecycles (development, procurement, support).
• Assessing and improving an organization’s capability to deliver usable, accessible systems.
• Integrating HCD with systems engineering, quality management and procurement processes.
• Developing competence, training and certification programs for UX, HCI and human factors professionals.

Typical users:

• UX designers, human factors and HCI professionals
• Product managers and system engineers
• Quality managers and auditors
• Procurement officers and contract managers
• Executives and governance teams seeking to embed usability and accessibility across the enterprise
