# Coda: Judy

**The book's closing turn.** Judy survives because she gets up changed — that is
the book's argument throughout. The coda's single question is *who her getting up
is for*.

## A cartel can be viable

A cartel can be exemplarily viable, and so can a secret police, and so can a firm
whose product harms its customers slowly enough that they have not yet organized
to say so. The model will help each of them survive, in the same vocabulary and
with no change of tone. The manuscript's point is that this is not an objection
constructed to embarrass the model: it follows directly from what the model
claims. Viability is a capacity to persist under variety a system cannot fully
anticipate, and that capacity is indifferent to what the system is doing outside
itself. Nothing in the diagnosis distinguishes a hospital from a cartel.

The book adds that neutrality alone would be bad enough, and that the model is
also *useful*: a theory that gave a cartel bad advice would limit itself, and
this one does not fail there. Whatever you point it at, it makes better at
persisting.

## Viable for someone

A viable system is viable **for someone**. The model tells you whether the thing
you pointed it at can keep going; it does not tell you what to point it at.
Naming the system — deciding that this is the thing whose survival is at stake,
that these are its operating units, that its boundary runs here — is a decision
taken *before* the modelling starts. The manuscript quotes Beer making it the
method's first step, and records him writing that a system is "something defined
by intelligence" and that two people "will not necessarily agree on the
existence, or nature, or boundaries" of a system (DTS 1985: 2, 16; DC 1966: 242,
243, 246).

In practice the namer is whoever commissioned the work. The manuscript's charge
is that this is the most consequential act in an engagement and the one act the
method names and leaves without a procedure: which units get autonomy, which
flows count as coordination, what the intelligence function watches for, and what
the algedonic channel is wired to interrupt all sit downstream of a choice the
method treats as given.

## Different logical levels

Nothing in critical systems heuristics is incompatible with the VSM. The two
operate at different logical levels, and the habit of treating them as rivals has
cost the tradition a repair proposed decades ago — Jackson in 1988 and Flood and
Jackson in 1991, the manuscript notes, which the tradition did not take up.
Ulrich interrogates the boundary; Beer designs inside it. Each is the other's
missing half.

The manuscript's reading is that System Five and the algedonic channel are nearly
a witness function, and that the model has the mechanism while lacking a theory
of **who is entitled to use it**: membership is assumed, and there is no account
of standing for a party whose distress is caused by the system operating exactly
as designed. It calls the defect fixable, not refuting, and the cheapest
high-value reform available to the tradition.

## The standing test

A test the manuscript asks the reader to run on the last thing they built or
approved. Leave aside "did we engage stakeholders" and ask: **if every person
affected by this had said nothing at all, what would have happened?** If it would
have gone ahead exactly as it did, then whatever else was there, standing was
not. Consultation that changes nothing does not amount to standing; standing
means a signal from outside the membership can change the outcome.

## What the book has been walking toward

Viability is not a value but a capacity, and the choice of what to point the
model at is made outside the model by someone with interests. An instrument this
useful, in a tradition that has never stated what would count against it, is
described as a practical hazard: a community that cannot say what observation
would make it give something up cannot say what observation would make it decline
a piece of work either.

The coda's last ask is small and addressed to practitioners: **ask the question
in one engagement, in writing** — whose residual variety is this intervention
expected to increase, and whose will it reduce. The manuscript notes that
*residual variety* here carries the sense defined in [Chapter 26](https://wiki.cybernetic-futures.org/punch-and-judy/part-04-what-we-lose/ch26-freedom-as-quantity), not Beer's Third Axiom residue, and that the machinery for answering is already there.

## Status

Draft, *Punch and Judy* v0.5.0 — **not project canon**, and not published as a
book. The coda is an argument, not a finding, and the wiki reports it as the
manuscript's claim. Several Beer locators in this chapter are marked in the
manuscript as not yet checked against the printed pages.
