Boundary
A purpose- and observer-dependent distinction that marks what is treated as inside, outside or marginal to a system of concern and thereby shapes explanation, legitimacy and intervention.

Summary
A boundary makes inquiry and action possible by limiting what must be handled at once. It also externalises people, effects and responsibilities. Good systems work therefore treats boundary choice as practical, political and ethical.
Implications for practice
Boundaries decide who counts, what becomes a cost, which outcomes are visible and where responsibility stops. Changing the boundary can change the apparent problem without changing any events.
Key distinctions
- system boundary vs organisational border
- analytic boundary vs operational boundary
- inside/outside vs centre/margin
- temporary focus vs reified entity
- boundary judgement vs boundary object
Historical development
- general systems and system/environment distinction
- critical systems heuristics
- systemic intervention and boundary critique
- boundary-spanning practice
Ideas it depends on
- distinction
- observer
- purpose
- context
Further developments
- system of concern
- marginalisation
- transduction
- accountability
- intervention design
Connections to practice
- state the current boundary and purpose
- ask who and what is excluded
- test wider and narrower boundaries
- strengthen, suspend, cross, reframe or change boundaries deliberately
Common confusions
- the boundary is obvious
- wider is always better
- open systems have no meaningful boundaries
- organisational charts define the system
Further checks
- Midgley's full boundary critique
- Ulrich and CSH
- boundary objects
- boundary work in convening
