Systems theory

Summary

Systems theory is better read as a contested family of theories than as a single doctrine. Different traditions explain organisation, relation, boundary, feedback, emergence, hierarchy, viability or communication in materially different ways.

Implications for practice

Practice becomes muddled when a broad theoretical vocabulary is treated as one agreed worldview, or when explanatory models are converted into prescriptions without showing the translation.

Key distinctions

• one theory vs a family of traditions
• explanation vs intervention method
• formal, biological, social and organisational domains
• first-order modelling vs reflexive and second-order accounts

Historical development

• general systems theory
• cybernetics and information
• operations research and systems engineering
• complexity, autopoiesis and second-order cybernetics

Ideas it depends on

• Relation
• Organisation
• Boundary
• Observer

Further developments

• Systems methods
• Systems practice
• Systems science
• Cybersystemics

Connections to practice

• say which theoretical tradition is being used
• state the domain and limits of analogy
• show the move from explanation to action
• retain rival accounts where the field is not settled

Common confusions

• that all systems theories are compatible
• that theory automatically provides a method
• that using system language removes observer dependence
• that a formal model supplies its own purpose and ethics

Further checks

• develop a comparative history of major systems-theory traditions
• map incompatible uses of system, organisation, information and complexity
