The best case studies to teach management and face the challenges of modern business

If people learn best by hands-on experience, the case study method is the next best thing. It introduces students to a professional facing a concrete problem — often based on or inspired by a real business. It provides relevant background information and asks students what they would do in that professional’s shoes.

IESE has long championed the use of case studies, which expose learners to a wide variety of both common and industry-specific business scenarios. Professor Jordi Canals once described them as “a stimulus to creativity, intellectual rigor and balanced reflection on management issues.” José Ramon Pin in his book on what makes a case study a success or a failure, adds that this teaching method drives us to know ourselves: By reflecting on why we made one decision and not another, we learn to analyze our own priorities and thought processes.

We’ve gathered a selection of new and inspiring case studies. Together, they highlight some of the greatest challenges of the present moment, from the ethical implications of ChatGPT, to evergreen challenges on sustainability and strategic partnerships, to what our globalized world can learn from local traditions.

Does the new profitability mark a lasting shift or a one-year anomaly?
