Public-Private Partnership: There is no broad global consensus on what comprises a public-private partnership (PPP). Generally, PPP refers to arrangements, usually medium to long term, among the public and private sectors whereby fraction of the services or works which fall under the responsibilities of the public sector are given by the private sector, with obvious agreement on shared objectives for delivery of public infrastructure and or public services. This usually does not comprise service contracts or turnkey construction contracts, which are classified as public procurement projects or the privatization of utilities where there is a limited ongoing role of the public sector.
