Knowing as intervention: Reflections on the application of systems ideas

The relation between theory and practice is explored in this paper with respect to an examination of various systems approaches. It is argued that the moment of knowing already contains practical implications in that comprehensiongears practice in certain directions. Practice/application can fulfill the demands of theory through the operation of a self-fulfilling prophecy effect. The way in which theoretical conceptions of systems researchers may constrain practice is explored with reference to the work of Beer, Checkland and Scholes, and Ulrich. In the course of this exploration, alternative views of the way in which viable systems diagnosis, soft systems methodology, and critical systems heuristics may be utilised, are offered.
