The author suggests to clearly know what the goals of a case study are before starting to write it. He states that in most cases, the straightforward approach without contradictions poses enough challenge without confusing asides and red herrings. The author also advises that it is important to consider the level of experience the students have with case studies, keeping them simple if the students have little to no experience. The more experience the students have, the more additional information you can provide. He states that it is also important to decide how much class time can be spent on the case studies, which will help determine the limitations that need to be set.
