Abstract: This paper presents a study which examines several e-government success factors in developing countries. Developing countries in the Middle East have a history of commitment to good governance and ICT-related initiatives. But still there is very little research that examines what businesses use in terms of e-government and issues and constraints that they face, plus that e-government projects failure cases mostly happen in developing countries, hence there is a need to give a great deal of attention to these countries to make e-government projects successful. For a better understanding of e-government and its influence on the society as all and on the business society in particular the researchers carried out a study to propose a conceptual model for e-government success and to identify the success factors which affect e-government success from a business perspective in developing countries, and to investigate the factors that determine business organization satisfaction towards e-government in developing countries. In this paper the researchers will discuss four factors that affect the success of e-government services from businesses perspective in developing countries as followed: information quality, perceived ease of use, personalization and trust.
