The document discusses public-private partnerships (PPPs) models for e-governance and analyzes Singapore's e-Procurement project (GeBIZ) as a case study. Key PPP models for e-governance include build-own-operate-transfer, build-own-operate, and build-operate-transfer. GeBIZ was a successful PPP between the Singapore government and a private partner to create a centralized online procurement system. The project increased transparency, reduced costs, and saw over $10 billion in online transactions by 2005. The document concludes that PPPs are a viable model for developing e-governance solutions when customized to each country's needs.
