Zeven plus of min twee

…er is teveel werk voor een persoon. Wát? Er is werk voor heel veel personen.

✣ ✣ ✣

Een bruisend, productief en zinnig team.

't Is niet omdat Jeff Sutherland en Ken Schwaber dit gezegd hebben. 't Is omdat er beperkingen zijn aan de menselijke capaciteit van informatieverwerking.

2 mensen zijn slimmer dan 1.
3, 4, 5, 6, 7, 8 en 9 mensen zijn slimmer dan 2.
een groep groter dan 9 mensen is gewoon één grote domme klont.

Een klein team met slimme en capabele mensen kan veel meer doen dan een groep van 10 middelmatige mensen.

Eén van de oorzaken is gebrek aan goede communicatie. Grote teams zijn een voertuig voor slechte communicatie. Het aantal communicatiekanalen tussen n personen is van de orde n². Met 5 personen zijn er dus 10 communicatiekanalen, met 9 personen zijn dat er al 36, met 10 zijn dat er 45. Het wordt onhandelbaar. Hoe schaal je dit op? Als een holarchie (een broccoli).

George A. Miller schrijft:

The span of absolute judgment and the span of immediate memory impose severe limitations on the amount of information that we are able to receive, process, and remember. By organizing the stimulus input simultaneously into several dimensions and successively into a sequence of chunks, we manage to break (or at least stretch) this informational bottleneck.
The process of recoding is a very important one in human psychology and deserves much more explicit attention than it has received. In particular, the kind of linguistic recoding that people do seems to me to be the very lifeblood of the thought processes. Recoding procedures are a constant concern to clinicians, social psycholo- [p. 96] gists, linguists, and anthropologists and yet, probably because recoding is less accessible to experimental manipulation than nonsense syllables or T mazes, the traditional experimental psychologist has contributed little or nothing to their analysis. Nevertheless, experimental techniques can be used, methods of recoding can be specified, behavioral indicants can be found. And I anticipate that we will find a very orderly set of relations describing what now seems an uncharted wilderness of individual differences.
The concepts and measures provided by the theory of information provide a quantitative way of getting at some of these questions. The theory provides us with a yardstick for calibrating our stimulus materials and for measuring the performance of our subjects. In the interests of communication I have suppressed the technical details of information measurement and have tried to express the ideas in more familiar terms; I hope this paraphrase will not lead you to think they are not useful in research. Informational concepts have already proved valuable in the study of discrimination and of language; they promise a great deal in the study of learning and memory; and it has even been proposed that they can be useful in the study of concept formation. A lot of questions that seemed fruitless twenty or thirty years ago may now be worth another look. In fact, I feel that my story here must stop just as it begins to get really interesting.
And finally, what about the magical number seven? What about the seven wonders of the world, the seven seas, the seven deadly sins, the seven daughters of Atlas in the Pleiades, the seven ages of man, the seven levels of hell, the seven primary colors, the seven notes of the musical scale, and the seven days of the week? What about the seven-point rating scale, the seven categories for absolute judgment, the seven objects in the span of attention, and the seven digits in the span of immediate memory? For the present I propose to withhold judgment. Perhaps there is something deep and profound behind all these sevens, something just calling out for us to discover it. But I suspect that it is only a pernicious, Pythagorean coincidence.

Daarom:

Kies voor een zelfselecterend team van zeven plus of min twee leden. Splits bij de overgang van negen naar tien en fuseer zodra je onder de vijf komt.

Opschalen tot een holarchie. Houd rekening met het getal van dunbar en de wet van conway.
