Harvard Business School has been among the most prominent developers and users of teaching case studies . Business school faculty generally develop case studies with particular learning objectives in mind . Additional relevant documentation, such as financial statements, time - lines, and short biographies, often referred to in the case study as exhibits, and multimedia supplements (such as video - recordings of interviews with the case subject) often accompany the case studies . Similarly, teaching case studies have become increasingly popular in science education . The National Center for Case Studies in Teaching Science has made a growing body of case studies available for classroom use, for university as well as secondary school coursework .

Teaching case studies need not adhere strictly to the use of evidence, as they can be manipulated to satisfy educational needs . The generalizations from teaching case studies also may relate to pedagogical issues rather than the substance of the case being studied . </P> <P> Case studies are commonly used in case competitions and in job interviews for consulting firms such as McKinsey & Company, CEB Inc. and the Boston Consulting Group, in which candidates are asked to develop the best solution for a case in an allotted time frame . </P>
