1) Agile development is feedback driven.
2) Development teams need to keep testing quick, simple, and frequent.
3) Agile UX must be flexible. It must respond to end user feedback and market changes in one iteration (one week).
That is what ScreenZest provides for them. It is better than other methods of user validation like Interviews, In-house usability tests, Focus groups, Surveys, Beta tests, and Demos. They are just too slow.
It appears what we are selling is “Fast User Validation” –not “Reduced Bounce Rate”.
