 | Objectives Public Service Infrastructure (PSi) is a central facility that allows quick and efficient deployment of e-services by offering 'built-once, reuse-always' components such as payment, authentication and data exchange to the government agencies | Most government agencies develop services that perform fairly similar functions – collecting payment,authenticating customers, ensuring security, collecting or exchanging data with other agencies. This can be a fairly long development lifecycle that is likely to be repeated for most e-services. By leveraging on the building blocks of PSi, Singapore's Public Service Infrastructure shortens the development cycle. Its infrastructure, application services and e-service development environment allow agencies to rapidly develop e-services. Components such as payment, authentication and data exchange, are ‘built-once, reuse-always' services that agencies do not need to develop on their own. By leveraging these building blocks, development time is drastically reduced from months to days. The Singapore Government's PSi initiative won the Intelligent 20 Award and the prestigious Explorer Award at E-GOV 2002 in Washington DC, America. It also won the CIO Award in 2001.
