Abstract:

Just as companies need to differentiate themselves by creating and promoting a clear value proposition, so do UX groups. What is our value proposition? What can UX teams do that other disciplines cannot? We think in terms of design. We communicate visually. Nobody else can do this as well as we can. Other disciplines may do a much better job of communicating numbers in spreadsheets or giving slick presentations highlighting features. What we, as UX professionals, can do is bring possibilities to life by visualizing solutions for stakeholders and enabling them to see those possibilities in tangible form.
