The ECCH distributes cases from many business schools, holds workshops on case teaching and on case writing and lists other case workshops of different business schools.
They have a user friendly website. Teaching Faculty can register for free case downloads. They have over 2000 cases – many are shorter and less complex than the typical HBS cases.
