How might we "help the daring build design legendary companies"? In this hands-on portfolio workshop at Sequoia Design Lab, we collaborated with the founder James Buckhouse and designer Aine Zhou to learn how they “diagnose with data and treat with design.” We began by examining a case study framework, then explored designers’ portfolios using the case study framework, and concluded with tactical and practical skills and resources. And how could we forget the delicious Sprinkles cupcakes?
