Checked the definition, attribution and stated distinctions against the listed source passages.
- Stafford Beer, The Viable System Model: its provenance, development, methodology and pathology (1989)
Beer’s own account of recursive organisation, five functions and Chilean application.
What this check doesn’t establish
- Selected parts of Beer’s retrospective account checked; no independent test of the model’s sufficiency.
Confidence applies to the scope above, not every claim made by the underlying source. How confidence works
Beer’s model distinguishes operational units and the functions that coordinate, control, adapt and set policy for them. Recursion is central: operational units can themselves be modelled as viable systems.
The law of requisite variety informs the model but is a distinct principle, not another name for it. The five-function architecture is Beer’s theoretical account of viability, not a guarantee that an organisation described in those terms will succeed.
