"The use of case studies as a basis for teaching in the intelligence profession requires a body of well-crafted cases and case studies that are relevant to the needs of students and faculty. There are a number of prospective sources for such material. External sources include civilian academic institutions such as the John F. Kennedy School of Government at Harvard. The JFK School's catalog includes several dozen cases and case studies that may be appropriate for classroom use. This is particularly true for courses that feature the relationship between intelligence and national security policy; about a dozen JFK School cases examine this relationship in detail. Most of this material was created under a contract between the JFK School and the Central Intelligence Agency (CIA)'s Center for the Study of Intelligence. JFK School cases and case studies explore strategic issues, whereas CIA material addresses the tactical or operational levels of war, where many if not most JMIC graduates will spend their intelligence careers."
