Three instruments: a ten-point quiz, eight reflection questions, five essay prompts. The quiz checks comprehension rather than recall. The reflections are private and first-person. The essays are arguable from more than one side.
Four on recall.
1. Define a holon, and name its two faces.
A holon is simultaneously a whole and a part. Inward it is self-assertive — it holds its own rules and its own right to act over what it contains. Outward it is integrative — it serves the larger system that contains it. One mark for the whole/part definition, one for naming both faces. Koestler's image is Janus. An answer that gives only the inward face has described a breakaway unit, which is the failure mode, not the concept.
2. State Ostrom's eighth design principle.
For common-pool resources that are parts of larger systems, appropriation, provision, monitoring, enforcement, conflict resolution and governance activities are organised in multiple layers of nested enterprises. Credit any answer naming multiple layers. The principle rules out single-layer governance — in either direction, purely local or purely central.
3. Write the escalation function and define each term.
L(c, d) = (1 − (1 − c)^d) / c, wherecis the containment rate — the share of decisions a unit closes without escalating — anddis the depth of the tree in levels.Lis the expected number of levels a decision traverses before it closes.
4. What does a nested structure have to add back in order to keep its benefits, and why?
A declared exception clause with a pre-named commander, a time box and automatic reversion; a named integrative role with no line authority; and a written contract between peers. The first exists because an emergency sets containment to zero. The second and third exist because Freeman's mechanism — informal, undeclared structure forming along friendship networks — operates in any group that declines to write its structure down.
Four on application.
5. A colleague says: "We are going flat — we are removing a whole layer of management." What has been misunderstood?
That nesting is a change to the escalation rule, not to the tree. A nested structure of 10,000 people in teams of 12 at a span of 5 is still 6 levels deep — the same depth as the hierarchy. What changes is that a decision rises only when it cannot be contained, rather than rising until it meets authority. The stronger answer notes that removing a layer without raising the containment rate raises coordination cost, because the same decisions now traverse the remaining levels by consent.
6. A self-managed team has grown from twelve to nineteen people and reports that everything feels harder, though nobody can say why. Diagnose it.
Mesh coordination grows as
h(h−1)/2. At twelve there are 66 possible ties; at nineteen there are 171. The per-team crossover at which a managed hub becomes cheaper than a mesh ish= 12.47 people, with a band of 10.46 to 14.16; the organisation-wide crossover at equal containment is 18.82. The team is past both. Full marks note that the cost is invisible because it is distributed across everybody's calendar rather than sitting in a salary line.*
7. Someone cites Haier's RenDanHeYi as proof that microenterprise structures raise profitability. How should that claim be handled?
As testimony, not evidence. Haier publishes no microenterprise-level accounts; every quantitative account in the management literature rests on company-supplied data and company-arranged access, over a period containing four large acquisitions including GE Appliances at about $5.6bn. What can be computed is the headcount arithmetic — about 10,000 middle-management roles removed. Credit any answer that separates what is reported from what is derived, and does not therefore dismiss the case.
8. Why is an emergency the worst case for a nested structure specifically, rather than merely a hard case for any structure?
Because an emergency is definitionally an event that spans units, which sets the containment rate to zero.
L(0, 6) = 6: the decision climbs the entire tree by consent. At five working days a level that is 30 working days against 5 under unity of command — twenty-five lost. The stronger answer gives the fix rather than the complaint: a time-boxed exception clause with automatic reversion, rehearsed.
Two that require the arithmetic to be done.
9. A firm of 3,000 people runs teams of 10 at a span of 6. Compute the number of teams, the depth, the managerial headcount, and the escalations saved per decision if the containment rate rises from 0.50 to 0.80. Show your working.
Teams = 3,000 / 10 = 300. Depth =
ceil(log₆ 300) + 1= ceil(3.18) + 1 = 5 levels. Nodes above teams =ceil(299/5)= 60; plus 300 team leaders = 360 managers, 12.0% of the front line.L(0.50, 5) = (1 − 0.5⁵)/0.5 = 1.9375;L(0.80, 5) = (1 − 0.2⁵)/0.8 = 1.2496. Difference = 0.6879 escalations per decision. At 24 decisions per person per year that is 72,000 decisions, and at £270 a level the escalation saving is £13.37m a year. Credit any method reaching 0.68–0.69. The point of the question is that the answer is a cost line, and a cost line can go in a plan.
10. For the same firm, compute the break-even containment rate c*, given that the hierarchy's total coordination cost is £44.88m and the nested structure's fixed cost — coaches plus mesh — is £8.55m.
The escalation budget left to nesting is £44.88m − £8.55m = £36.33m. That buys
L = 36,333,000 / (72,000 × 270) + 1 = 1.8690 + 1 = 2.8690levels. SolvingL(c, 5) = 2.8690givesc= 28.2%. The stronger answer states the conclusion in the right register: this firm's nested structure has to close only a little over a quarter of its decisions locally to be the cheaper structure — and the threshold is low precisely because it is carrying 342 fewer coordination posts to begin with.*
These are not for a room. Write the answers by hand if you can; the slowness is the point.
Each is arguable from more than one side. Each requires at least one source the chapter cites and at least one it does not.
1. Is flatness a claim about structure or about the work? The chapter argues that a nested structure is the same tree as a hierarchy, and that all the measured benefits follow from the containment rate rather than from the number of levels. Argue either that this collapses a real political distinction into an engineering one, or that the political framing has cost the field thirty years of evidence. Use Simon on near-decomposability, and one source on organisational design or the sociology of work that the chapter does not cite.
2. Freeman, fifty years on. "The Tyranny of Structurelessness" was written about the women's liberation movement in 1972. Argue whether its mechanism transfers intact to a commercial firm — where exit is cheap, pay is formal and there is a legal employer — or whether the transfer is a rhetorical convenience that flattens two very different settings. Engage Freeman directly, and at least one empirical study of informal hierarchy in firms that the chapter does not cite.
3. Buurtzorg's counterfactual. KPMG found roughly 40% fewer hours of care per client and an overhead gap of 17 points. The study is not a randomised trial, and client mix, nurse qualification and self-selection all differ from the comparators. Write the strongest case that the Buurtzorg result is a structural effect, then the strongest case that it is a selection effect, and say which you find more persuasive and why. Use KPMG or Gray et al., and one source on selection bias in health services evaluation that the chapter does not cite.
4. The case for managers. Foss and Klein argue that the bossless-company literature systematically undercounts what managers do — particularly under uncertainty, where judgement cannot be decomposed into contracts. Take a position on whether the containment instrument in this chapter answers them or evades them. You will need to be specific about what c does and does not measure. Use this chapter's arithmetic and Foss and Klein, plus one source on managerial judgement or the theory of the firm that the chapter does not cite.
5. The exception that became the rule. Every structure in this chapter carries a way to become temporarily hierarchical, and every one of them risks never handing command back. Argue whether automatic reversion by date is a sufficient safeguard, drawing on a case outside management entirely — emergency powers in constitutional law, incident command in wildfire or aviation, or clinical escalation in a hospital. Use Weick and Sutcliffe or the FEMA incident-command doctrine, and one source from that outside domain that the chapter does not cite.
