Great quote from Cordell Ratzlaff, Director of User Experience at Cisco (ex-Apple and frog design, and speaking at the upcoming MX conference in San Francisco):
“One of my pet peeves is with the specialized labels that have evolved within our profession. We have user interface designers, usability engineers, user experience specialists, visual designers, interaction designers, etc. The distinction between these many roles is fuzzy and confusing to those both inside and outside the design profession…I encourage designers to get as broad a range of experience as possible. Design products for as many markets, demographics, product types, and technology platforms as you can. Don’t be afraid to take on tasks outside your traditional role. The best designers I know are good at many facets of design. It certainly doesn’t hurt to know about branding, marketing, business models, and technology as well.”
