The business worth of a computer system is a function of its quality in use - the extent to which it is fit for its purpose. The ISO/IEC 9126-1 standard (Software Product Quality Model) places quality in use as the overall goal for software development. Using the term quality in use to describe usability recognises that software does not exist in isolation, but must fit with a human work environment if it is to be useful in practice. Usability as quality in use is increasingly recognised in industry as a primary goal in developing business systems and IT products.
The presentation will explain how new ISO standards under development can be used to support user centred design and integrate usability requirements and usability test results into the software development and procurement processes
