Salmons mentions the work of Robert Yin and Robert Stake. Yin outlines four fundamental types of case studies on the basis of the number of cases and units of analysis in the study design. Stake divides case studies into three types: intrinsic — a single case an individual, group, organization, event, or other entity that is important in its own right, not necessarily because of its potential predictive theoretical powers; instrumental — a single case where the focus is on going beyond the case to understand a broader phenomenon of interest; and collective — a multiple case version of instrumental where the focus is on learning about a phenomenon. Unlike Yin, Stake is not linking his case studies to the idea of testing preconceived theories but rather to the idea of using the peculiarities of any particular case to illuminate the phenomenon and magnify the understanding of the research topic. This internal-external classification, and its relationship to the Yin and Stake typologies, is shown below. In this internal-external classification, an intrinsic case study as defined by Stake, with its emphasis on what can be learned about the specific case itself, is classified as an internal type of design because the research findings will only be used to inform that specific case. An example of an internal case study is research that a healthcare organization might conduct to investigate its new patient-referral program to inform their need for new social media solutions.

The art of case study research. Introduction: An Intensive Study of Case Study Research Methods "Case study is the study of the particularity and complexity of a single case, coming to understand its activity within important circumstances xi. Intrinsic and Instrumental Study Stake identifies three types of case study: intrinsic case study, instrumental case study, and collective case study. An intrinsic case study occurs when the researcher has an intrinsic interest in the case. An instrumental case study occurs when we need to understand the case in order to understand the bigger research question at hand.
