Critical Systems Heuristics (CSH)

Summary

Critical Systems Heuristics is a framework for reflective and critical practice which makes boundary judgements and their consequences discussable.

Implications for practice

CSH provides a disciplined way to examine who benefits, who decides, what counts as knowledge and how those affected can challenge claims to improvement.

Key distinctions

• is vs ought
• involved vs affected
• boundary judgement vs neutral fact
• heuristic vs algorithm

Historical development

• C. West Churchman
• Werner Ulrich
• critical systems thinking

Ideas it depends on

• boundary
• purpose
• legitimacy
• knowledge
• power

Further developments

• twelve boundary questions
• boundary critique
• citizen competence

Connections to practice

• policy appraisal
• evaluation
• participative inquiry
• professional critique

Common confusions

• CSH discovers the correct boundary
• the twelve questions are a checklist survey
• only emancipatory projects can use CSH

Further checks

• add primary book sources
• connect systemic marginalisation
• develop cases and criticism
