User experience and usability are key ingredients of any successful mobile app. In this workshop, Phil will describe the differences between the two as important elements of software quality from the end user viewpoint. User experience, in particular, is an element that many forget until the end and generally don’t know how to measure since there are no standard definitions. Phil will discuss quality modeling and how usability and user experience should be modeled for the enterprise. This discussion will range from the initial components of quality, to breaking usability and user experience down into measurable characteristics for mobile apps, and then, using these characteristics to derive metrics. These metrics can then be used to benchmark, analyze, and improve the app toward end user satisfaction. Beyond this, Phil will also review a case study where various measurements were implemented to show actual usability improvement.
