ISO/IEC 25019:2023 defines the Quality-in-use model within the Systems and software engineering - Systems and software Quality Requirements and Evaluation (SQuaRE) framework. It is relevant for organizations that need a structured basis for evaluating how software or a system performs in actual use, rather than only against internal design requirements. For engineering teams, testers, and procurement reviewers, ISO/IEC 25019:2023 supports more consistent technical assessment, documented evaluation, and quality workflows where usability, effectiveness, and operational outcomes matter.

Overview of ISO/IEC 25019:2023

This document is part of the ISO/IEC 25019 series and serves as a supporting technical reference connected to the parent reference ISO/IEC 25019. Its focus is the quality-in-use model, which is commonly used to describe how a product or system should be evaluated in real operational conditions. In practice, it can help teams define review criteria, align verification activities, and structure technical validation around user-centered outcomes. That makes ISO/IEC 25019:2023 useful in engineering documentation and compliance preparation.

Compliance applications of ISO/IEC 25019:2023

Organizations may use ISO/IEC 25019:2023 when preparing evaluation plans, reviewing software performance from the user perspective, or documenting quality expectations for product acceptance. It is especially relevant where technical assessment must support procurement decisions, conformity assessment preparation, or internal quality assurance. The model may also help laboratories and engineering groups create more consistent testing workflows for systems where operational consistency and measured user impact are important, even when the broader solution includes complex integrated software components.

Importance of compliance with ISO/IEC 25019:2023

Using ISO/IEC 25019:2023 helps organizations make quality-in-use expectations clearer and more traceable during development, testing, and acceptance. That can reduce risk when evaluating whether a system meets practical performance criteria in real use, not only formal specifications. It may also improve interoperability discussions, support regulatory preparation, and strengthen procurement reviews by giving stakeholders a shared technical basis for comparison. For quality assurance and engineering validation, the document can improve consistency in documented evaluation and review.
