This paper relates this comparison to a more general debate of how different research designs contribute to a theory continuum.
The fine-grained analysis demonstrates that case study designs fit differently to the pathway of the theory continuum.
These differences result in a portfolio of various case study research designs.
Second, I outline and substantiate a theory continuum that varies between theory-building, theory development, and testing theory.
This paper aims to delve into a deeper level of analysis by solely focusing on case study research designs and their respective fit on this theory continuum.
This approach offers a more fine-grained understanding that sheds light on the diversity of case study research designs in terms of their differential theory contributions.
The resulting contribution is a portfolio of case study research designs.
This portfolio demonstrates the heterogeneous contributions of case study designs.
The objective of this paper is to highlight similarities and differences across various case study designs and to analyze their respective contributions to theory.
Although different designs reveal some common underlying characteristics, a comparison of such case study research designs demonstrates that case study research incorporates different scientific goals and collection and analysis of data.
