In an increasingly globalized world, the challenges of society need to be tackled not by single organisations but by a multitude of stakeholders. Universities can contribute by extending their role and by collaborating with external stakeholders. This study employs qualitative methods to explore how a university engages with its innovation ecosystem through two different projects.The findings, connected to the development of educational and digital systems, show: 1) evidence of two extreme approaches to external stakeholder engagement and 2) three levels of tensions (multi-layered tensions) - on an overarching level, between stakeholder groups, and within groups of stakeholders. The contribution connects to literature on open innovation, quadruple helixes and lastly to university social innovation, especially responsibility diffusion.
