This paper addresses the topic of this special symposium issue: how to enhance the impact of cross-sector partnerships. The paper takes stock of two related discussions: the discourse in cross-sector partnership research on how to assess impact and the discourse in impact assessment research on how to deal with more complex organizations and projects. We argue that there is growing need and recognition for cross-fertilization between the two areas. Cross-sector partnerships are reaching a paradigmatic status in society, but both research (...) and practice need more thorough evidence of their impacts and of the conditions under which these impacts can be enhanced. This paper develops a framework that should enable a constructive interchange between the two research areas, while also framing existing research into more precise categories that can lead to knowledge accumulation. We address the preconditions for such a framework and discuss how the constituent parts of this framework interact. We distinguish four different pathways or impact loops that refer to four distinct orders of impact. The paper concludes by applying these insights to the four papers included in this special issue.

The intensification of cross-sector collaboration phenomena has occurred in multiple fields of action. Organizations in the private, public, and social sectors are working together to tackle society’s most wicked problems. Some success has resulted in a generalized belief that cross-sector collaborations represent the new paradigm to manage complex problems. Yet, important knowledge gaps remain about how cross-sector alliances generate value for society, particularly to its beneficiaries. This paper answers the question: How cross-sector collaborations lead to systemic change? It uses a (...) qualitative embedded case study design. I use two general cases of alliance-based interventions in the developing country Colombia. Embedded cases within each general case identify evidence of collective action capacity of the beneficiaries. Findings identify and explain alliances’ contributions to beneficiaries’ capacity building: brokering trust and creating spaces where beneficiaries develop an emergent collective action capacity. Alliances also enable beneficiaries to enact that capacity by building bridges, circulating capitals, and buffering relationships to protect people’s initiatives. Alliances and empowered collectives of beneficiaries produce systemic change using five mechanisms: brokering trust, creating spaces, building bridges, circulating capitals, and buffering relationships. Beneficiaries increased capacity for collective action is an outcome that becomes an alliance input, leading overtime to further benefits involving systemic change. (shrink)
