Given today's global work environment, business education should prepare learners not only for technical excellence but also for effective collaboration. In this article, the author describes how collaborative activities--ranging from exams to projects and role playing--enhance the understanding of operations management (OM). The author found that collaborative learning improved undergraduate business students' understanding of quantitative OM methods, developed their strategic-thinking skills, and enhanced their confidence in their critical-thinking and implementation skills. The exercises also increased students' comfort level in communicating and working with their peers and enhanced their independent learning skills. (Contains 4 tables.)
