Case studies that are fit for Harvard style involves controversial decisions by the protagonists. There may be errors of judgment on their part, but this does not remove their competence in the field, and it also must not negate the fact that the errors are not out of a badwill. Because of these, you have to ensure that a thorough check is done before you ever pick a topic for your Harvard case study. This is to make sure that the situation is exactly what you think. It is always good to ensure that what you see is what you get. Think about the problem at the core of the case and understand the things the readers will like to know. This is what will propel you. You must focus on the things they should know about the players, context, and efforts to solve the problem. There are two main errors you must avoid whenever you are writing this type of case study. You must avoid leaving your readers with scanty information about the case that will make them not to understand the problem. You must also avoid unnecessary information that will divert their attentions from the core points of the study. You are not writing a literary analysis essay here, so it must be about what happened in the first place and not the things surrounding it. Give the raw event before you add your own views.
