The real-time case consists of several components:  Some communication is one-way, and consists of 1) background material on the case company's industry and technology, 2) weekly case installments, 3) "breaking news" reports, and 3) conceptual articles related to the problem of the week. Two-way interactivity between the case company and the students includes video conferences, phone conferences, and online chat sessions.   Finally, the excitement of the case is enhanced by competitions between schools, and by the opportunity for students to make input to the case company's decisions.
