Organizational consultancies has been spreading and influencing more and more the every-day life of organizations. In some markets, enough room can be found for little and middle sized firms providing this service. Nevertheless, the increasing need for specialization, which narrows competencies and structures, stimulates the formation of networks where consultants supplement and articulate themselves. In order to study this field, whose particularities are still unknown, the present article takes as reference the theory of social networks, mainly the factors of their formation. These factors were sought in the report of professional consultants, first in an on-line survey of ninety of them. Secondly, results were commented in-depth by a group of experienced consultants. Generally, findings are aligned to main factors of full social immersion networks (GRANOVETTER 1973; 1985). However, personal trust in the other consultant - inseparable of technical competence - and in the associate consultancy, as well as ethic behavior, stand out. They become manifest in rules, though not written, and they support other factors of formation and maintenance of network.
