The energy transition requires a workforce equipped with both hard and soft skills. However, current training often emphasizes technical competencies, resulting in skill
mismatches, particularly among professionals transitioning from fossil fuel sectors. To support a just and inclusive transition, boundary spanning skills are essential for
aligning diverse stakeholders and navigating complex systems. This study, conducted within the Sprong SURE consortium, explores how Mission Mapping and Systemic Constellations, two participatory systemic co-design tools, can contribute to the development of these competencies in regional energy transition experimentation areas. By
engaging a diverse group of stakeholders, the tools facilitated the sharing of perspectives, the building of trust, and the development of systemic awareness. Thematic
analysis and grounded theory revealed that these tools enhance communication, stakeholder alignment, and informal leadership across boundaries. Although these tools are currently used at the end of projects, the findings suggest that they could be even more effective if used earlier on to highlight system dynamics and blind spots. Future
research should investigate the optimal timing and conditions for applying these tools to further empower professionals in the energy transition."
