User Experience Grading via Kano Categories

摘要

A consistent challenge in product development is determining whether a product meets its usability requirements. In particular, accurate, meaningful usability information is hard to obtain before product release. This paper describes a method to classify use cases, features, and requirements into Kano model categories and then grade each based on how well is has been implemented from a usability perspective. Using this method during product development can provide early, regular data on the status of product usability, help to determine where resources are spent, and perform competitive analysis based on product features and usages. This method was tested on a single case study, and in particular for the requirements of the user interface for a discrete video card.
