The Ring Without Her
She stops for a while. Between rounds it is fair to ask whether any of this was worth the damage, and whether the club would miss her at all if she did not come back. It would: watch the fights she is not in, and something is missing that nobody else is attempting. The claim she is left with is narrower than she once thought, and this part states it exactly.
Part Two conceded almost everything. Others found the components of the model independently, described them more carefully, and in several cases measured them. So what remains that is ours? The answer fits in a sentence. Defending it takes five chapters.
Chapter 23, The Narrow Claim, fixes the proposition and names four things that do not follow from it. Chapter 24, Six Things Nothing Else Does, tests whether the assembly, as distinct from its parts, is unique. Chapter 25, The Transducer, places regulatory loss at the crossing of a boundary; the usual remedies, more reporting and more bandwidth, look for it in the channel. Chapter 26, Freedom as a Quantity, returns to freedom as Beer stated it in The Heart of Enterprise, as something commensurable with the diagnosis, where the tradition has usually treated it as a value asserted alongside it. Chapter 27, What Might Replace the VSM, hands each job the model does to whoever does it better and states the residue that has no other home.
One rule governs this part, and we state it as a rule so that nobody has to infer it: every credit carries its concession in the same breath. Nothing is claimed here without what it costs, what it has not been tested against, or what it cannot do, and that goes in the same paragraph, not in a later chapter or a footnote. The reason is not modesty. For fifty years this tradition has produced lists of virtues with the concessions left off, and Chapter 9 shows that a statement of that form cannot be wrong. To repeat the form here, in a part whose whole subject is what we are entitled to claim, would undo the book.
The stake is real. Part Four is written so that it could come out empty. If, after Chapter 27, the residue is nothing that another literature does not do better, the conclusion follows without appeal: the tradition should be wound up and its useful pieces handed on under other names. We would rather establish that than keep the tradition alive by lowering the test until it passes. A claim narrowed to the point of survival is worth something only if the narrowing was done in public and could have gone the other way.
