The document compares and contrasts B-schools and D-schools (design schools). B-schools focus on traditional business curriculum taught through case studies and exams. In contrast, D-schools like Stanford's d.school teach design thinking through collaboration, prototyping, and real-world challenges. Students learn by tackling open-ended problems and producing prototypes, often resulting in new companies and products that solve user needs in innovative ways. The d.school aims to help students develop creativity, comfort with ambiguity, and a mindset of experimentation and risk-taking.
