Beschreibung der Methode: 

A case study (CS) is an empirical inquiry that investigates a contemporary phenomenon (the ‘case’) in depth and within its real-world context, especially when the boundaries between phenomenon and context may not be clearly evident. (YIN 2014: 16)

Case Study/Fallstudie

Eine Fallstudie (Case Study - CS) ist eine empirische Untersuchung, die ein zeitgenössisches Phänomen (den "Fall") eingehend und in seinem realen Kontext untersucht, insbesondere wenn die Grenzen zwischen Phänomen und Kontext nicht klar erkennbar sind. (YIN 2014: 16)

Case Study (Case studie)

En case studie - CS) er en empirisk undersøgelse, som undersøger et nutidigt fænomen ("Sagen") nærmere og dens reale kontekst, især når grænserne mellem fænomen og kontekst ikke er klart synlige. (YIN 2014: 16)


From the B4R document “THE CASE METHOD TOOL AS A COLLABORATIVE B4R PLATFORM” (Per Servais, 2016):
The main characteristics of case studies, according to Nicky Hayes (2000), include:
1. A descriptive study
(I.e. the data collected constitute descriptions of psychological processes and events, and of the contexts in which they occurred (qualitative data).The main emphasis is always on the construction of verbal descriptions of behavior or experience but quantitative data may be collected. High levels of detail are provided.
2. Narrowly focused
Typically a case study offers a description of only a single individual, and sometimes about groups. Often the case study focuses on a limited aspect of a person, such as their buying behavior.
3. Combines objective and subjective data
The researcher may combine objective and subjective data; both are regarded as valid data for analysis and as a basis for inferences within a case study—the objective description of behavior and its context, as well as details of the subjective aspect, such as feelings, beliefs, impressions or interpretations. In fact, a case study is uniquely able to offer a means of achieving an in-depth understanding of the behavior and experience of a single individual.
4. Process-oriented
The case study method enables the researcher to explore and describe the nature of processes which occur over time. This method contrasts the experimental method, which basically provides a stilled ‘snapshot’ of processes that may continue over time, such as the gradual development of language in children.
