IMD’s EasyJet case remains the bestselling and most‑used case in MBA classrooms worldwide, Poets&Quants reports, underscoring the staying power of strategy‑driven teaching materials. Authors and faculty say the EasyJet story distills competitive strategy, marketing and execution into a single narrative that instructors can deploy across disciplines from operations to entrepreneurship. The case’s longevity — a quarter century on the bestseller list — reflects faculty preference for compact, debate‑driving materials that force students to choose tradeoffs rather than seek a single answer. Strategy and leadership cases continue to dominate the Top 50 list maintained by The Case Centre, highlighting demand for real‑world decision exercises in graduate management education. Business schools should note the continued curricular value of classic cases even as institutions add tech and data modules. Case selection remains a lever for aligning pedagogy with program strengths and employer expectations.
