Abstract

ISO has recently developed a new more comprehensive definition of quality in use, which has usability, flexibility and safety as subcharacteristics that can be quantified from the perspectives of different stakeholders, including users, managers and maintainers. While this provides a more complete set of requirements for operational use of a product, it also presents new challenges for measurement.
