S13-404: Evaluating and Improving Mobile App User Experience

Track: Mobile Application Testing

Today’s web and mobile applications containing complex business logic and sometimes critical to operating the business, now must have an increased focus on usability as well as the newer and broader term, user experience. Especially with SaaS based business models where users can switch applications at a heartbeat and pay by the month (or even a free trial), both usability and user experience become paramount as there is no up-front investment forcing a user to stay. The ISO 25010 standard describes a model for general usage in specifying and evaluating software quality requirements, one of which is usability, but there are no models or formal definitions for user experience, nor its relation to usability. UX has no formal standard definition, although some models have been developed regarding its elements.

In this talk, we draw relationships and definitions between usability and user experience and explore measurement and evaluation methods that can be used as the first step toward improvement for both mobile and webapps.

Session Takeaways:

  • Understand usability, user experience, and their differences.
  • Understand why it is important and how it impacts user acceptance and application success.
  • Methodology for continuous usability improvement.
  • Practical measurements and methods.
  • Learn how one organization improved UX via a case study.
