This short summary of Critical Systems Heuristics (CSH) by Werner Ulrich gives an overview of what CSH is and how it can be applied. CSH is a framework for reflective practice based on practical philosophy and systems thinking. The basic idea of CSH is to support boundary critique – a systematic effort of handling boundary judgments critically.
