Design services and the companies that provide them have changed. The changes are for the better, but these experience design (XD) providers' words and processes — whether around design thinking, interface design, service design, or product design, for example — often sound alike and blend together. To help, Forrester surveyed 51 XD providers, researched the relevant trends and types of providers, and identified the key questions customer experience pros and their colleagues must answer to make a smart decision. This report is a one-page overview graphic about the in-depth reports that present our findings from this research. It also links to those reports.
