Public–private partnerships (PPPs) have long been advocated as organizational solutions to pressing societal problems that call for the collective advantages of government, business, and civil society. However, questions remain about how best to design, manage, and oversee PPPs. This blog seeks to address these problems. It offers a discussion of partnership definitions and builds a framework that examines the features of PPPs as they relate to policy, service delivery, and capacity building in the security sector. The blog considers the role of different partners, the difficulties in finding a balance of interests and incentives among partners. It also examines the implications of promoting international good governance norms and values, the different sources of authority that operate within multistakeholder initiatives in the security sector.
