Critical systems thinking is a robust recent trend in humanistically oriented systems work. Spearheaded by work of Ulrich (1983), Flood (1990), and Flood and Jackson (1991), this approach manages to accommodate the knowledge-constitutive interests of Jürgen Habermas (1971) and the interpretive analytical orientations of Michel Foucault (1972) through a meta- methodology involving constant critical reflection. The meta-methodology serves as the basis for the generation of a new methodology that critically applies various systems approaches to problem solving.
