Summary
Peter Checkland developed Soft Systems Methodology through sustained action research in situations where purposes, boundaries and improvements are contested rather than given.
Implications for practice
His work makes a basic systems distinction operational: systems can be used as devices for inquiry into a situation without assuming that the situation itself is one objectively specified system.
Key distinctions
- system as ontology vs system as epistemological device
- hard problem solving vs inquiry into problem situations
- model of purposeful activity vs model of the world
Historical development
- systems engineering
- action research at Lancaster
- Soft Systems Methodology
- later systems practice
Ideas it depends on
- purpose
- boundary
- worldview
- learning
- human activity system
Further developments
- Soft Systems Methodology
- rich pictures
- root definitions
- conceptual activity models
Connections to practice
- organisational inquiry
- public-service problem structuring
- participative learning
- feasible and desirable change
Common confusions
- SSM is a softer version of optimisation
- a conceptual model describes the real organisation
- consensus is required before action
Further checks
- add Learning for Action
- map Checkland's collaborators and students
- develop criticism and later adaptations
