Edition chronology and bibliographic identity; limited support for the detailed reading note.
- Stafford Beer: Death is equifinal — references
Beer’s own bibliography identifies the 1972 book and expanded 1981 second edition.
- OpenLibrary work API: Brain of the firm
Inspected work title and linked author identities; catalogue identity does not establish a particular edition or validate the content.
- OpenLibrary linked author record
Author identity checked against the linked catalogue work; not used to establish the work’s factual argument.
What this check doesn’t establish
- Bibliographic reference inspected, not the complete book. The VSM and Cybersyn interpretation needs chapter-level checking; removed the unsourced attribution to Raul Espejo.
Confidence applies to the scope above, not every claim made by the underlying source. How confidence works
Beer's exposition of the Viable System Model, his framework for describing the structures an organisation requires in order to remain viable in a changing environment. The model is set out by analogy with the human nervous system, in five recursive subsystems.
The second edition adds material on Project Cybersyn, in which Beer applied the model to the Chilean economy, making the book a participant account of that project as well as a statement of the theory.
This reading note interprets the book as both a theory of organisational viability and a participant account; the present review checks its edition history, not that interpretation in full.
Primary source for Project Cybersyn.
