Team Training (TT) is a well-established method for enhancing team performance. It has been applied in domains such as healthcare, aviation, and military, as a structured process to develop skills, knowledge and attitudes to team members work cohesively towards shared goals.

Currently, TT programs face six critical challenges:
(i) achieving sustainability in large-scale programs,
(ii) addressing cross-cultural and virtual team dynamics,
(iii) creating reusable and domain-independent training models,
(iv) integrating advanced technologies (e.g., Intelligent Tutoring Systems),
(v) understanding emergent states such as trust and cohesion, and
(vi) fostering interdisciplinary collaboration despite epistemological differences.

To address these challenges, we developed the ABC (Aprendizagem Baseada em Coprodução, or Coproduction-Based Learning) methodology. ABC is an interdisciplinary framework grounded in six key components:
(1) Educational Commons, to establish the principles, components and coproduction purpose for team learning;
(2) Hybrid Emergent Temporary Teams, to offer tools to mediate the learning teams as dynamic, diverse and temporary groups;
(3) Competence-Based Learning, to ensure skill development through active teaching methods;
(4) User-Experience Digital Educational Design, to enhance learner engagement;
(5) Digital Education, to support large-scale instructional delivery; and
(6) Digital Communication, to enable scalability and accessibility.

ABC combines these components to create a coproduction-based process, facilitating team learning through digital education and mediated group dynamics. ABC is the latest development from the Digital Commons Coproduction Research Group at the Graduate Program in Knowledge Engineering and Media (PPGEGC), Federal University of Santa Catarina (UFSC), Brazil. It is a direct result from CEURS Program – a national initiative to train municipal agents in localizing Sustainable Development Goals (SDGs), and it is an independent-domain approach to large-scale capacity development projects.

This paper presents ABC methodology, detailing its development, structure, and implementation in two different domains. We illustrate its application through two major projects, demonstrating its contribution to capacity-building and interdisciplinary collaboration. ABC addresses key TT challenges and advances practical and theoretical approaches to large-scale capacity building in complex settings.
