Abstract:

The Software Usability Measurement Inventory is a rigorously tested and proven method of measuring software quality from the end user's point of view. SUMI is a consistent method for assessing the quality of use of a software product or prototype, and can assist with the detection of usability flaws before a product is shipped. It is backed by an extensive reference database embedded in an effective analysis and report generation tool.
