WORKBOOK — THE STUDENT

Chapter I.10 · Scaling Without Losing the Thing

For the person learning this before they have anything to scale. That is an advantage, not a handicap: every organisation you will ever join is somewhere on one of these curves, and almost nobody inside it has computed which point.

WHY THIS WORKBOOK IS DIFFERENT

You are going to be told, for the whole of your working life, that things need to grow. You will rarely be told what growth costs the thing being grown, and you will almost never be in a room where someone has the arithmetic.

You can have the arithmetic by the end of this term. It rests on three expressions and none of them is hard:

  F(k) = φ^k                        what survives k teaching hops
  B(n) = B_max · (1 − e^(−n/k))     shared benefit per unit, saturating
  C(n) = c · (n − 1) / 2            coordination per unit, in a mesh of peers

The first tells you how far a practice can travel. The second and third, set against each other, tell you how large a group of equals can usefully be. The answer to the last one — about twenty-four for the optimum, about eighty-seven for the ceiling, on realistic parameters — is smaller than almost anyone believes, and you can compute it for any group you are actually in.

That is the skill. Not opinions about scale. A number, for this group, with the workings attached.

PART ONE — DISCOVERY

Days 1–30: find the thing that already travels

Exercise 1.1 — The hop map (one week)

Pick something you do that you were taught by a person: a technique, a recipe, a way of running a rehearsal, a method for a lab procedure, a style of coaching.

1. Who taught you? Who taught them? Go back as far as you can — four or five hops is usually reachable by asking.
2. For each hop, write one thing that was passed on with its reason attached and one thing that was passed on as a rule with no reason.
3. Now go forward. Who have you taught? What did they keep?

Output. A diagram with the source at one end and you somewhere along it, and a note at each hop of what arrived and what did not.

You are looking for a specific and slightly uncomfortable moment: the point in the chain where somebody started doing something because they were told to, rather than because they understood it. That point is where φ dropped, and it is always identifiable in retrospect.

Exercise 1.2 — The four-box sort (2 hours)

Take any organisation you have genuine access to — a society, a sports club, a student newspaper, a part-time employer, a family business — and sort what it does into the four boxes.

Most organisations put things in the wrong boxes. Find one that is in the wrong box and write two sentences on what that error is costing.

Exercise 1.3 — The appreciative interview (three conversations, 30 min each)

Interview three people who run something that has more than one location, branch, chapter or team. One question, held open:

"Think of the branch or team that is furthest from where this started and is still unmistakably the thing. What made that one work?"

Do not ask what goes wrong. You will hear about what goes wrong anyway, and you will hear it as an aside rather than as a complaint, which is where the real information is.

Output. Three pages of notes on conditions, not outcomes.

---

PART TWO — THE ARITHMETIC

Days 31–45: compute before you have an opinion

Exercise 2.1 — Fidelity, by hand (2 hours)

Work these without a spreadsheet, on paper, then check them.

1. At φ = 0.90, how many hops until half the thing is gone? ln(0.5)/ln(0.9) = 6.58 — seven.
2. At φ = 0.90 and a floor of 0.70, how many hops are allowed? ln(0.70)/ln(0.90) = 3.39 — three.
3. At φ = 0.85, same floor? ln(0.70)/ln(0.85) = 2.19 — two.
4. Now the point of the exercise: what does lifting φ from 0.85 to 0.90 do to the size of the network you can hold inside the floor? Two hops at four trainees each is 25 units. Three hops is 85. A five-point improvement in teaching quality more than triples the reachable network.

Write one paragraph on what that implies about where a growing organisation should spend its money.

Exercise 2.2 — The ceiling, for a real group (one week)

Take a group you are in — a society with chapters, a league, a network of student branches — and estimate its three parameters. You will be estimating, and that is fine, as long as you say so and show how.

• B_max. What does a member get from the group that they could not get alone? Price it: discounts, shared insurance, a name on a CV, a venue, access.
• k. At what membership was most of that already available? Ask two long- standing members.
• c. What does one member-to-member relationship cost a year? Count the meetings, the messages, the travel, the reconciliations. Value the time at a rate you can defend.

Then compute:

  n* = k · ln(2·B_max / (k·c))
  and the n at which  B(n) − c(n−1)/2  turns negative

Output. One page: the three parameters, how you estimated each, the two numbers, and one sentence on what this group should do about it.

Exercise 2.3 — The honest negative (1 hour)

Every model in this chapter has a condition under which it misleads. Find one and write 200 words on it. Some real candidates: the mesh model assumes every member must deal with every other, which is false for groups with a strong informal centre; the fidelity model assumes hops are independent, which fails when everyone reads the same manual; the saturating benefit assumes new members add nothing distinctive, which is wrong for a federation that scales variety rather than volume.

Choosing a good objection to your own model is the single most examinable skill in this volume.

Exercise 2.4 — Read one case properly (3 hours)

Pick one of the four families in the chapter and go to a primary source: Whyte and Whyte on Mondragón, Rubin on the franchise contract, Davis and Stokes on the Champlain resales, or the NCUA's own annual statistics on credit union counts and membership. Not a summary and not an encyclopaedia entry — the actual text or the actual table.

Write 300 words answering two questions. What number in the chapter can you now verify from the source? And what did the source say that the chapter left out? The second question is the real one. Every secondary account compresses, and the thing that gets compressed out is usually the condition under which the case does not generalise.

PART THREE — DREAM AND DESIGN

Days 46–70: build something that travels

Exercise 3.1 — Write the portable organ (one week)

Take the group from Exercise 2.2. Name the one thing every unit currently does separately and would rather do once. Then write its specification on two pages:

1. What it does, in one sentence.
2. What it costs to run, per year, roughly.
3. How it is funded — and the rule from the chapter: a levy capped as a percentage of measured benefit, never of member revenue.
4. Who governs it. One member, one vote, regardless of size.
5. How a member leaves: notice period, what they take, and their data.

This is a real document. Groups adopt these. Write it as though yours will.

Exercise 3.2 — The transmission design (3 days)

Design how a new unit of your chosen thing would be created, with the hop rule written in:

• Who trains a new unit, and how far are they from the source?
• What is the retrain trigger, stated as a rule and not a feeling?
• What does the source do to keep φ high — and what would raise it by five points?

Include the visit. Every one of the four families in the chapter transmits partly by somebody from the source spending a week doing the work alongside a distant unit. It is expensive, it does not scale, and it is why the rest scales.

Exercise 3.3 — The ceiling clause (1 hour)

Write the clause. Three sentences:

At n = ___ members this group clusters into sub-groups. At n = ___ it stops admitting members until it has. Both numbers are recomputed each year from measured B, k and c, and the workings are attached to the annual report.

Take it to whoever runs the group. Note what happens. The reaction is the finding.

---

PART FOUR — DESTINY AND DELIGHT

Days 71–90: make it hold, and enjoy it

Exercise 4.1 — The failure walk (2 hours)

For your designed structure, write the four ways it dies:

1. The second tier becomes the principal and the units become branches.
2. Growth is counted in units rather than units-above-the-floor.
3. It admits past its own arithmetic and the meetings stop being worth attending.
4. One person is still the transmission mechanism at unit forty.

For each, write the first observable sign and who would see it first. The second column matters more than the first: an early warning nobody is positioned to see is not an early warning.

Exercise 4.2 — Go and stand in one (one day)

Visit a distant unit of something — a branch of a chain, a chapter of a society, a member of a cooperative group — and spend a day there. Write 400 words on what was unmistakably the thing and what had drifted. Be specific about the drift: not "standards were lower" but "the greeting was a script, and at the source it is not."

Exercise 4.3 — Design one delight deliberately (1 hour)

Delight is the adoption mechanism, not the reward. Design one thing into your structure that a member would actually look forward to — the annual gathering that is genuinely good, the visit that is a pleasure rather than an inspection, the moment a new unit is recognised by name. Write what it is and what it costs.

If your structure contains nothing anyone would look forward to, it will need to be enforced, and enforcement is the most expensive coordination there is.

THE TERM PROJECT

One piece of work, carried the whole way

Choose one real group with more than one unit — a society with chapters, a small chain, a network, a club with branches, a family business with two sites — and produce its scaling case.

Deliverables.

1. The hop map (1 page). Every unit, its distance from the source, and how you established it.
2. The three parameters (600 words plus workings). B_max, k and c, each with its estimation method stated, and the two computed numbers.
3. The four-box sort (1 page). What in this group is a system, a profession, a standard, an invention — and which instrument each implies.
4. The organ specification (2 pages). The one thing they should build once.
5. The ceiling clause (3 sentences), delivered to a named person who could act on it.
6. The honest negative (400 words). The condition under which your own analysis is wrong, argued as strongly as you can argue it.

How it is assessed. Not on whether the group adopts anything. On whether a reader could reproduce your three parameters from your stated method, and on the quality of item 6.

An analysis with a strong objection to itself is a first-class piece of work. An analysis that recommends growth without computing a ceiling is not.

---

SELF-ASSESSMENT

Score yourself honestly. This is for you.

The two that matter most are the fourth and the sixth. The others are technique. Those two are dispositions, and dispositions take a term.

---

CARRYING IT FORWARD

You will not run a federation for some years. What you will have, if you do this properly, is:

• The ability to put a number on "how big should this be", on request, in a room where nobody else can.
• A hop map habit, which will tell you within a week of joining any organisation how far its practice has travelled from whoever understood it.
• One written organ specification, which is a document people adopt.
• The instinct to ask what shape before what size — which is the whole chapter in four words.

That last one is worth more than it sounds. Almost every organisation reaches its coordination ceiling and interprets it as a strategy problem. The person in the room who recognises it as a topology problem changes what the room is able to decide, and they do not need any authority at all to do it.

APPRECIATIVE QUESTIONS FOR YOUR SEMINAR

1. When has one of you belonged to something distant that still felt unmistakably like the thing? What made that work?
2. Which groups we belong to have already passed their own ceiling, and what would clustering look like for one of them?
3. What is the highest-fidelity transmission any of us has experienced, and what was the teacher doing that nobody wrote down?
4. If this seminar had to design one portable organ that every student group on this campus could use, what would it be?
