The document discusses the evolution of e-government and the emergence of open government as the next stage. It outlines three generations: (1) informatization, (2) e-transformation focused on citizen services, and (3) open government which is participatory, accountable, and citizen-driven. The World Bank can help build an open government ecosystem by leveraging its role as a global knowledge broker, trusted partner, and architect of an ecosystem approach. Examples of key components and World Bank e-government projects in various countries are also provided.
