Collaboration between the state, economy, and civil society requires cross-sectoral cooperation to pool core competencies and resources. This enables the realization of economies of scale and synergies, leading to comprehensive and innovative solutions. Martin Holzberg derives implications for the successful design and management of cross-sectoral cooperation based on a survey of cooperation managers from the state, economy, and the third sector. He demonstrates that depending on the combination of cooperating sectors and the sector perspective considered, there is a varying emphasis on relevant success factors.
