A designer’s job doesn’t end when the best experience is captured in mocks or even prototypes. It’s only complete when that experience is shipped and in people’s hands. This often hinges on how well design collaborates with their engineering counterparts. In this talk, Tina Chen (Sr Product Design Manager @Slack) and Garrett Miller (Sr. Engineer at Slack) go through some examples of design and engineering partnerships that allow both roles to thrive and rapidly ship polished products. They discuss about how to build strong design and engineering relationships, bringing engineering in early in the product design process, how to conduct design and technical explorations in parallel, and how to communicate specs and polish without introducing friction.
