The team used a collaborative design process that involved personas and UX principles to make design decisions. They conducted card sorting, created site maps and user flows, reviewed personas, created rough sketches, refined ideas by merging them, created wireframes individually and then reviewed as a team, and iterated on the navigation, product pages, and home page before user testing. The process resulted in a home page mock-up and lessons learned around refining wireframes and prototypes and setting expectations for user testing.
