Writing a Case is a 7-hour independent study in which you will write a case story to use in case study with a training audience. This independent study should take 2- 4 weeks to complete. If you’ve ever used scenarios as a training technique, case study is a higher level version of scenarios. Trainees read and discuss a case story to arrive at their own conclusions and course of action. A well-written case story can lead trainees to the teaching objective you had in mind.
