==Frameworks and methodologies==
Frameworks and methodologies for systems thinking include:
* Critical systems heuristics:<ref name="ulrich" >{{cite web|author=Werner Ulrich|url=https://projects.kmi.open.ac.uk/ecosensus/publications/ulrich_csh_intro.pdf|date=1987|title=A Brief Introduction to Critical Systems Heuristics (CSH)}}</ref> in particular, there can be twelve boundary categories for the systems when organizing one's thinking and actions.
* [[Critical systems thinking]], including the [[Critical systems thinking#Recent developments|E P I C]] approach.
* [[DSRP]], a framework for systems thinking that attempts to generalise all other approaches.
* [[Ontology engineering]] of representation, formal naming and definition of categories, and the properties and the relations between concepts, data, and entities.
* [[Soft systems methodology]], including the [[Soft systems methodology#CATWOE|CATWOE]] approach and [[rich pictures]].
* [[Systemic design]], for example using the [[Double Diamond (design process model)|double diamond]] approach.
* [[System dynamics]] of stocks, flows, and internal [[#Feedback control systems|feedback loop]]s.
* [[Viable system model]]: uses 5 subsystems.
