SIST EN ISO 9241-115:2024 PDF

Overview

EN ISO 9241-115:2024 (ISO 9241-115:2024) is a CEN-adopted ergonomics standard that gives practical guidance for the design of human–system interaction. It covers four interrelated areas: conceptual design, user–system interaction design, user interface design, and navigation design for interactive systems. The standard applies across development approaches - human-centred design, object‑oriented, waterfall, HFI, agile and rapid development - and is intended to support consistent, usable, and accessible user experiences.

Key Topics

The standard addresses technical topics and design recommendations that drive usable interfaces and navigation:

• Conceptual design: defining system purpose, user needs, and high-level models that guide interface structure and behaviour.
• User–system interaction design: specifying interaction scenarios, types of interactions, and user actions the system must support.
• User interface design: structure of interfaces, interface instances and elements, information architecture, and information design strategies.
• Navigation design: designing navigation sequences and structures (linear, tree, network, hybrid, dynamic) and selecting navigation techniques to meet user goals.
• Human-centred design considerations: integrating user mental models, constraints on design, overall consistency, aesthetics, and support for appropriate interface technologies.
• Accessibility and device support: guidance for supporting different target devices and ensuring accessibility across user groups.
• Evaluation and conformance: guidance for evaluators and project teams to verify design recommendations are applied.

Note: EN ISO 9241-115:2024 supersedes EN ISO 14915-2:2003 and is part of the broader ISO 9241 ergonomics family.

Applications

This standard is practical for teams and roles involved in producing interactive systems:

• User interface designers: apply design guidance during solution concepting and UI specification.
• Developers: translate interaction and interface guidance into implemented functionality.
• Evaluators and usability testers: check that products meet ergonomic and navigation recommendations.
• Tool and style‑guide designers: build UI frameworks and templates aligned with ergonomic guidance.
• Project managers: integrate human-centred and usability goals into development processes.

Typical applications include websites, mobile apps, enterprise software, embedded systems, user interface libraries, and style guides - anywhere that clear information architecture, navigation, usability and accessibility are required.
