ABSTRACT
From the perspective of the systematic reviewer, case studies represent an important category of primary study, largely because they provide a very relevant way to study many software engineering topics. Unfortunately though, the term case study has often been used rather loosely to describe what are really rather informal observational studies. And as a further complication, the term “case study” may also be used to refer to a large-scale teaching example, particularly when used in the context of business and management studies (a “teaching case study”).
