Public private partnerships (PPP)represent an approach to procuring infrastructure servicesthat is radically different from traditional publicprocurement. It moves beyond the client-supplierrelationship when government hires private companies tosupply assets or a service. PPP is a partnership betweenpublic and private to achieve a solution, to deliver aninfrastructure service over the long term. It combines thestrength of the public sector’s mandate to deliver servicesand its role as regulator and coordinator of publicfunctions with the private sector’s focus on profitabilityand therefore commercial efficiency. There is a tendency toapproach reform of the PPP framework as a single action,generally delivered by external consultants in one massivereport, with a few workshops and training sessions (in aneffort to deliver the guidance in a more digestible form).Achieving a viable PPP framework involves a complex seriesof parallel, iterative initiatives, and efforts. It involvesupdating the different elements of the PPP frameworkdiscussed in this text as each new lesson is learned fromPPP transactions as they are implemented and national bestpractice as it develops. Section one introduces theframework required to support PPP and provides a summary ofthe text. Sections two to six describes five key elements ofthe PPP framework and what the government can do to improve them.
