# The Heart of Enterprise

1979 (John Wiley, Chichester). Abbreviation: **HOE**.

In [Pure VSM — Overview](https://wiki.cybernetic-futures.org/pure-vsm/overview), HOE develops the same [Viable System Model](https://wiki.cybernetic-futures.org/pure-vsm/entities/viable-system-model) as [Brain of the Firm](https://wiki.cybernetic-futures.org/pure-vsm/entities/brain-of-the-firm) from variety, without the neurophysiology. The "Glossary of Rules for the Viable System" (HOE 1979: 565–567) is "the most compact authorised summary". Not project canon.

## Where it is drawn on

Heaviest in [Part I — Foundations](https://wiki.cybernetic-futures.org/pure-vsm/part-01-foundations) ch. 3 (rules) and ch. 2 ([Variety and regulation](https://wiki.cybernetic-futures.org/pure-vsm/concepts/variety-and-regulation)). Across [Part II — The Viable System Model](https://wiki.cybernetic-futures.org/pure-vsm/part-02-the-viable-system-model): [System Two](https://wiki.cybernetic-futures.org/pure-vsm/concepts/system-two)–[System Five](https://wiki.cybernetic-futures.org/pure-vsm/concepts/system-five), [Law of Cohesion](https://wiki.cybernetic-futures.org/pure-vsm/concepts/law-of-cohesion), [Principles and axioms of organization](https://wiki.cybernetic-futures.org/pure-vsm/concepts/principles-and-axioms-of-organization), [Pathologies of viable systems](https://wiki.cybernetic-futures.org/pure-vsm/concepts/pathologies-of-viable-systems). Also Part III chs 17, 19.

## Formulation notes

From [Pure VSM — Appendix](https://wiki.cybernetic-futures.org/pure-vsm/pure-vsm-appendix): First Principle "minimal" vs "minimum" (HOE 1979: 97 vs 565); Recursive System Theorem "from the opposite angle" (HOE 1979: 118 vs BOTF 1981: 228); Law of Cohesion adds "for every recursive pair" (HOE 1979: 355 vs 567); System Two as a service, "damping oscillations, and nothing else" (HOE 1979: 177); six vertical channels (HOE 1979: 142–143 vs DTS 1985: 81–82); variety as "the measure of complexity" (HOE 1979: 45); Principles 2–4 and Axioms, body vs Glossary.

## Punch and Judy

Punch and Judy reads HOE as containing Beer's own concession that variety cannot be counted absolutely (HOE 86–87), his declaration that freedom is “a computable function of systemic purpose as perceived” which he never computed (ch 26), and the transducer principle he never measured (ch 25); the authors mark these as their readings of what the tradition shelved, not established findings.
