With the global emergence of e-government and its potential benefits to citizens in all its endeavors, there has been a growing need for research on drivers influencing the adoption of e-government services. This paper focuses on drivers influencing the adoption of e- government services among business organizations; hoping to have a better delivery of government services, the increased transparency and availability of information, and the improved interaction with businesses.

Jordan is currently striving to move forward in egovernment. However, figures reported in the Economist Intelligence Unit's (EIU) E- Readiness Ranking Report for the year 2008, Jordan ranked 53 out of 70 among countries with respect to its business environment. Also, Jordan ranked 50 among 192 countries according to the UN Global survey of e- government readiness in 2008. This paper aims to review the relationship between e-business and egovernment in general, as well as e- government and ebusiness readiness indicators particularly in Jordan. In addition, it examines the motivators and barriers for adopting e- government among business organizations. Jordan needs to overcome barriers for adopting egovernment among businesses, and reduce the gap between e-government and e-business with a mutual effort from both parties.

E-government is growing to a size that requires full attention from governments and demands collaboration and facilitation between private sectors and Non-Government Organizations (NGOs). In order to reach successful e-government applications, governments have to provide services to citizens, businesses and government agencies. In Jordan, e-government applications are limited to an informative goal; they essentially offer information and no services. Moreover, it is found that the traditional peer-to-peer integration of applications will result in a tightly coupled system that reduces the agility and expansibility of the E-Government system. This paper proposes a novel integration mechanism based on the web service of the Service Oriented Architecture (SOA) for the various E-government systems. We propose a stage model for E-Government interoperability based on Service Oriented Architecture (SOA). In addition, a framework for E-government based on SOA is proposed. The proposed architectures are being examined using case study in the context of implementing environmental license web service in the Jordanian ministry of environment
