In this study we focus the enhancement of experience of the participants in development projects with the specific purpose to identify mechanisms to address the participant’s technical level. We used an interventionist approach exploring two mechanisms (the knowledge truck and ambassadors) for knowledge transfer. A fish-producing regional network in the rural region of Cauca, Colombia, is used as case. The study contributes to technology transfer literature by expanding our knowledge about barriers created by low technical knowledge among technology receivers. Further the study contributes to the bottom-up approach to technology transfer.
