The primary delivery models of e-Government can be divided into:

• Government-to-Citizen or Government-to-Customer (G2C)
• Government-to-Business (G2B)
• Government-to-Government (G2G)
• Government-to-Employees (G2E)

Within each of these interaction domains, four kinds of activities take place

• pushing information over the Internet, e.g: regulatory services, general holidays, public hearing schedules, issue briefs, notifications, etc.
• two-way communications between the agency and the citizen, a business, or another government agency. In this model, users can engage in dialogue with agencies and post problems, comments, or requests to the agency.
• conducting transactions, e.g: lodging tax returns, applying for services and grants. • governance, e.g: online polling, voting, and campaigning.
