This article aims to establish a parallel between the organizational models and the didactic architectures used by businesses to manage internal training. The objective is to understand whether so-called "eLearning 2.0" (eLearning based on the tools and approaches typical of web 2.0) can be useful in different frameworks and organisations. In this context, the paper looks at whether it is possible to identify a mutual process of adaptation among the organizational and training models we term didactic architectures.
