From the Introduction: "A private-public partnership (P3) is any type of mutually beneficial cooperative arrangement, informal or formal, between two or more organizations of private industry and the public sector to enhance the life safety, economic security and resilience of jurisdictions. To highlight the value of the private sector, nongovernmental organizations (NGOs) and other stakeholders, this guide deliberately uses 'private-public partnership.' Without mutual benefit and effort on both sides, the partnership will not succeed. Activities to establish, support and maintain P3s already exist; however, most jurisdictions are not actively or consciously leveraging their full potential. The focus of this document is to build P3s that provide shared benefit across jurisdictions"
