Among the many debates about the new productive systems designed to go
beyond the Ford/Taylorist model, the notion of ''organizational learn
ing'' constitutes one of the better ways to analyze the effectiveness
of the ''models'' in question. This theory is applied to two, now clas
sical, cases: Nummi and Uddevalla - a Japanese transplant in the USA a
nd an original experiment in Sweden. With reference to these two cases
, learning is theorized as an evolving process of both diffusion and i
nnovation. This theory is broader than the much too static image conve
yed by the notion of a model. Actors and the organization jointly part
icipate in selecting and retaining knowledge, which alone can effectiv
ely respond to the ups and downs of production and the marketplace.
