This paper exposes the problems and challenges organizations face when integrating aged systems, web based systems and web services. The paper focuses on how people with different titles in an organization experience systems integration and the factors that contribute to project failure or success. The research methodology used in this is Grounded Theory and the resulting theory of this paper has taken form through the coding of transcribed interviews, which have gone through a constant comparing to other theories in the area of interest, mostly articles about success factors in system integration. The resulting outcome is a success model aimed to describe the underlying indicators to achieve project success. The success model consists of three factors that contribute to success in integration projects. The factors are: globalization, governance and balance. Integration projects are very complex in nature, more so than normal projects as there are more stakeholders involved and more interests to take into consideration. Due to the complex nature of integration projects, the need for a holistic view arises. It's crucial for an integration project that stakeholders take the interests and needs of other projects taking place simultaneously into consideration. The governance aspect of systems integration deals with the planning of strategies, communication and cooperation with other stakeholders involved within the integration project. It's crucial for integration projects to shift focus from individual goals and individual interest to mutual goals and interests. The third and final factor contributing to success in integration projects is balance. The balance between technical issues and organizational issues is crucial for the success of projects. It's very common that organizations focus on technical issues and neglect the organizational issues.
