2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/147037We present a detailed model of collaboration in communities of practice and we examine its dynamical consequences for the group as a whole. We establish the existence of a novel mechanism that allows the community to naturally adapt to growth, specialization, or changes in the environment without the need for central controls. This mechanism relies on the appearance of a dynamical instability that initates an exploration of novel interactions, eventually leading to higher performance for the community as a whole.23 pages, postcript, uuencodedAdaptation and Self-Organizing SystemsCommunities of Practice: Performance and Evolutiontext
