Track: Test Strategy, Process and Design
Today’s web-based applications (WebApps) 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. Now, mobile apps are following their lead and are gaining more and more sophisticated functionality even with limited screen real estate. This has led to both usability and user experience becoming paramount as there is no up-front investment forcing a user to stay. Even though usability has some formal ISO model definitions, there are no models or formal definitions for user experience, nor its relation to usability. For usability, ISO provides general guidelines but lacks implementation specifics. UX, on the other hand, does not have any formal standard definition, although some models have been developed regarding its elements. Models and research have been used mostly for the purpose of understanding, rather than evaluating and improving. In this talk, we draw relationships between usability and user experience and discuss measurement and evaluation methods that can be used as the first step toward improvement. Specific measurements are shared in a case study.
- Understand usability and develop a usability model
- Understand why it is important and how it impacts user acceptance
- Methodology for continuous usability improvement
- Practical measurements
- Learn how one organization conducted usability testing via a case study
