A case study reports an individual or organization’s experience with a specific product, process, or service. It is often used to demonstrate the value of that product, process, or service.
Case studies are usually written by the company that offers the product, process, or service and are designed to show how it helped other people solve their problems.
The primary purpose of case studies is to illustrate how a particular solution has worked for one or more specific clients. Studies make an excellent marketing tool because they provide tangible evidence about the benefits of your product, process, or service..
