EN ISO 25065:2020 PDF

Overview

EN ISO 25065:2020 (ISO 25065:2019) is a Common Industry Format (CIF) standard in the SQuaRE family that defines a consistent framework and terminology for a User Requirements Specification (URS) focused on usability. It specifies the content elements and the format for stating user requirements so that interactive systems can be developed and evaluated against clear, measurable user-centred criteria. Adopted by CEN, this standard supports human‑centred design without prescribing a specific lifecycle or method.

Key topics and technical requirements

• Scope and purpose
  • Defines user requirements as both user‑system interaction requirements (what users need to do to achieve outcomes) and use‑related quality requirements (usability criteria such as effectiveness, efficiency, satisfaction).
• Types of user requirements
  • User‑system interaction requirements and use‑related quality requirements (aligned with ISO/IEC 25030 concepts).
• Content elements of a URS
  • Identification of the interactive system and predecessors/version history
  • Context of use (users, tasks, environment)
  • Goals and tasks to be supported
  • Constraints on design
  • Detailed user requirements: how to state them, required accompanying information, and structure for presentation
  • User interface design guidance to be applied
• Conformance and structure
  • Prescribes the format and essential elements for a consistent URS, facilitating traceability and evaluation.
• Interoperability with human‑centred processes
  • Intended to be used with outputs from ISO 9241‑210 (human‑centred design) and ISO 9241‑220, and to support iterative/agile development.

Practical applications and users

Who benefits:

• Requirements engineers, business analysts, product managers, product owners, and procurers acquiring interactive systems. Practical uses:
• Creating a formal URS to guide design, development and acceptance testing.
• Establishing measurable usability targets (effectiveness, efficiency, satisfaction) for procurement and supplier acceptance.
• Aligning user needs (ISO/IEC 25064) and context of use (ISO/IEC 25063) with design and evaluation deliverables.
• Supporting usability evaluation and test reporting by providing a consistent baseline for requirements.
