It is time to start researching. This research can include many different things, but usually focuses on interviews and observations.
The heart of the case study is the research notebook. Every researcher must have a physical notebook to record all finding, notes, and observations. While some computer programs and other technological advances can be used, nothing can replace the original research notebook.
Preliminary Research
Once you have chosen your topic, you must do preliminary research to determine whether the topic is viable or not. To do this, you can review newspapers, databases, industry websites, and other previously published case studies. With some topics, you might even want to discuss your idea with other people in your field.
You must be certain that you have access to enough information to accurately determine whether or not the topic is viable. It is always a good idea to have one or two backup ideas in the event your first idea doesn't pan out.
Once you have your topic, you must choose which perspective the story should be told.
