By watching their videos I got an impression that is too back-end
focussed. No much room for a 'rapid' UX mind-set. For that I tend to
stand for Axure. Light and fast prototypes with documentation. I have
no experience with iRise and depending on complexity it might bring
benefits to the requirements management and other parts of the
application development, e.g. back-end programming, test scripts and
so on. It looks overkilling to test UX, though.
Is someone, focused on UX, actually using it? For fast simulations in
an iterative design process? Testing with end-users?
