In this research note we describe a method for exploring the creation of causal loop diagrams (CLDs) from the coding trees developed through a grounded theory approach and using computer aided qualitative data analysis software (CAQDAS). The theoretical background to the approach is...

This article presents a conceptual framework and methodological guide for researching and understanding OR interventions particularly problem structuring methods (PSM).
