Leaders face growing connectivity, complexity, and unpredictability. Winning with Networks equips students to understand how relationships shape individual success, organizational performance, and competitive advantage. Drawing on network science and analysis of real data, the course examines social influence, network effects, innovation adoption, crowdsourcing, and collective intelligence. Students learn to strengthen personal and professional networks, launch and grow networks around new products, and get ideas adopted within organizations. Lectures, live experiments, network visualization exercises, and a team project provide opportunities to apply these concepts across business contexts. The course also explores how generative artificial intelligence (AI) changes network advantages, collaboration, and decision-making, while developing students' ability to use and evaluate AI-assisted analysis. Students leave with a practical toolkit for analyzing networks and translating insights into action. Developed jointly with Professor Uzzi, the course complements MORS-430 Leadership and Organizations.
