| Резюме≠ | Set-theoretic multimethod research (SMMR) integrates the cross-case logic of Qualitative Comparative Analysis with the within-case logic of process tracing. After QCA identifies the combinations of conditions that are necessary or sufficient for an outcome, SMMR uses the resulting solution terms to classify cases — typical, deviant, individually irrelevant — and to select cases for in-depth process tracing. Codified by Carsten Schneider and Ingo Rohlfing, it grounds the choice of cases and the search for mechanisms in set theory, so cross-case and within-case inference reinforce one another within a single, coherent framework. | Qualitative Comparative Analysis (QCA) is a set-theoretic, configurational method that identifies which combinations of conditions are necessary or sufficient for an outcome across a set of cases. Developed by Charles Ragin, it treats each case as a configuration of set memberships, builds a truth table of all logically possible combinations, and uses Boolean algebra to minimize them into the simplest expressions that account for the outcome. It bridges qualitative case knowledge and cross-case generalization, embracing causal complexity through conjunctural causation, equifinality, and asymmetry. |
