Let’s start out with a definition. A search on Google defines a case study as:
“A process or record of research in which detailed consideration is given to the development of a particular person, group, or situation over a period of time.”
We aren’t talking about academic case studies, so this definition will serve us well. For case studies of your clients, the focus will be on development in a specific area that is related to your product or service. It may be over a short period or long period of time, depending on what is appropriate for the particular case.
For example, if you’re a running coach and you have a client training for a marathon, you might focus on that specific training up to the date of the marathon. Or if you teach people how to relieve pain with yoga and meditation, you want to capture a period of time from where your client experiences daily pain to where most of the daily pain is relieved.
