Open Communities of Practice are used extensively in various domains to promote collaboration and knowledge sharing. They are frequently applied in developing open-source software and educational resources. This research investigates how Agile methodologies can excel in the activities and management of developing educational resources and drawing the data from the completed Erasmus+ project, as well as supported by the triangulation approach and semi-structured Interviews. This work identifies a few issues in working with cross-border projects, such as proper training, daily meetings to get feedback, frequent iterations, and the selection of software tools and tangible deliverables. In contrast, the Agile framework was not suited for loosely structured teams. Instead, Agile, or Agile-inspired steps, and adaptive collaboration with patience provide visible progress in digital collaboration environments. This study also offers potential practical recommendations for improving openness and engagement in new Erasmus+ projects.
