The use of business case studies, defined as sophisticated models that present practical business problems and theoretical guidelines that can be used to solve the problems, is discussed. It is suggested that the main advantages of case studies are that they are usually more interesting to read than theoretical materials and they encourage student participation. The cases are useful supplements to available business German texts. They are helpful in preparing students to pass objective business language examinations such as the German Business Certificate Test. Two sets of cases are cited that were developed for the third or fourth year level of language proficiency, one based on a series of articles in a monthly German business journal, and the other comprised of a series of connected cases that are related to the steps necessary to set up a new company. Among the topics covered in the cases are the following: flexible working time; changes in corporate culture; corporate takeovers; global management; product development; sales and distribution; personnel planning and hiring. It is concluded that the case study materials are an ideal way to introduce business and management topics and vocabulary, to facilitate speaking and interaction in class, and to provide interesting readings and points of discussion.
