Configurational Strategy Analysis (fsQCA)

Configurational strategy analysis applies fuzzy-set qualitative comparative analysis (fsQCA) to strategy questions, asking not which single variable drives an outcome but which combinations of conditions together produce it. The method rests on Charles Ragin's set-theoretic framework, fully developed in his 2008 book Redesigning Social Inquiry: Fuzzy Sets and Beyond, which treats causes as set-membership relations and uses Boolean logic to find the configurations of conditions that are sufficient for an outcome. Peer Fiss's 2011 Academy of Management Journal article brought the approach into mainstream strategy and organization research, showing how fuzzy sets can express organizational typologies and introducing the distinction between core and peripheral conditions. The defining premises are equifinality - several different recipes can lead to the same outcome - and causal asymmetry - the conditions for success are not the mirror image of those for failure.
