The International Journal of Business Management and Technology, 4(6). https://doi.org/10.30560/rfm.v2n2p372581-3889http://hdl.handle.net/10400.8/5767Focusing the study's focus on sharing tacit knowledge in non-profit organizations (NPOs), in Portugal and taking as a case study the Portuguese volunteer firefighter (FBs), we listed as objectives, the determination of the prevalence of lessons learned by sharing tacit knowledge and the identification of actions and measures for its promotion. A review of the literature on lessons learned and sharing of tacit knowledge allowed the identification of indicators that allowed the determination of its prevalence in the NPOs. A mixed methodology followed, where data collections were combined via interviews and questionnaires, which analysis of results made it possible to answer the established objectives. It was possible to perceive the difference of opinions between firefighters and commanders, regarding the prevalence of lessons learned, being necessary to implement actions and measures that allow the construction of a collective vision of these organizations, on the part of all the stakeholders. It was also possible to create a performance matrix, with actions and measures for this purpose, which promotes an increase in the lessons learned by sharing tacit knowledge.engSharing tacit knowledgeNon-profit organizationsLessons learnedjournal article10.30560/rfm.v2n2p37
