The need for process-driven design systems with evaluation and reporting requires effort and resources. The variety of usability test methods and complexity of product life cycle development contribute to variability in the quality and repeatability of UX outcomes. For organizations with a strong focus on process, the ISO standards in the 25000 SQuaRE series and the 9241-210, -220, -221 provide guidance on quality measures. These standards have been developed to support industry and national bodies. As our UX products become embedded in complex systems, these standards can take on increasing importance and support organizations in assessing their process capability and maturity.
ISO 9241-11:2018 provides a framework for understanding the concept of usability and applying it to situations where people use interactive systems, and other types of systems (including built environments), and products (including industrial and consumer products) and services (including technical and personal services). 2b1af7f3a8
