How Practices of Managing Partnerships Contributes to the Value Creation—Public–Social Partnership Perspective

In this paper, the authors aim to answer the question of which model of public management—Public Administration, New Public Management, or Collaborative Public Management—is conducive to achieving better results in the public-social partnership. We understand public⁻social partnership as an activity undertaken in collaboration between organizations operating both in the public and social sectors. We also claim that Collaborative Public Management fosters sustainability in partnerships and should therefore be preferred in partnerships that are focused on delivering social services. In particular, we aim to find out how management practices that are used in the public-social partnership contribute to the co-creation of public value. The article brings together theoretical insights and empirical data. First, we integrate insights from different strands of literature. Next, empirical data are derived from two main sources: first, a specific case of the public-social partnership established by 18 institutions and organisations, followed by quantitative research that was conducted in 173 partnerships in Poland. Based on the presented case study, analysis of the survey results and in-depth interviews (IDIs) conducted with the 18 leaders of the organisations constituting the partnership, the observed pattern revealed the dominance of the Collaborative Public Management model contributing to the success of the partnership. It was also identified what actions were taken by the manager of the partnership in order to maintain links between the partners, build trust, and win their support and legitimisation in public space—all of which are necessary to create public value, which in turn contributes to the sustainability of the partnership
