Personally, my main motivation for a career change to the UX world is a desire to help people; to clarify, to simplify, to allow them to do what they do without having to worry about the tools they’re using while doing “their thing”. The business or fiscal benefits of creating a seamless user experience are a close second though in terms of my motivations.
Maybe it’s because I’ve owned my own business for the last five years, but I’m really drawn to the ROI aspects of UX research. In my opinion a true winning solution is one that finds a cohesive and comfortable balance of user needs and ROI for the business entity.
All that leads me to the very efficient, collaborative and inexpensive way to prototype; Sketchboarding.
