By supporting or institutionalizing Communities of Practice (CoP) of strategic relevance, organizations promote collective learning and organizational innovation. Aiming at analyzing how companies are dealing with the CoP, from the conception of the idea, implementation steps, difficulties, achievements and future challenges, this exploratory research was conducted at Elektro Eletricidade S.A., which configures the seventh largest distributor in Brazil, with a market share of 4% and a workforce of 5,205 employees. We conducted semi-structured interviews with those responsible for the project and analyzed documents (reports, projects, press news, etc.). The results showed that the success of each CoP is related to the degree of motivation of the participants and the role of facilitator responsible.
