| dc.description.abstract | Research on e-Government (e-Gov) is quite abundant. One of intriguing research topics is about how e-Gov would gradually develop in time and two types of models concerning the integration of information systems have appeared in the literature. Some researchers argue that information systems have to be integrated vertically first, rather than horizontally. On the other hand, some researchers advocate there is no particular order for the system integration. These two different points of view affect the development of the follow-up theories and practical applications as well. For clarification, this study conducted a case study based on Taiwan′s Immigration Clearance System (ICS), which is currently operated by Taiwan’s National Immigration Agency (NIA).
The aim of this case study was to find out the integration strategies behind the development and implementation of ICS and the factors that influence the decision making by the NIA. This study concludes in terms of information technology adoption that NIA uses vertical integration strategy first then horizontal for immigration management whereas vertical and horizontal integration occurs simultaneously for the development of ICS, and the integration process continues constantly in responding to new technologies that evolve from time to time.
In addition, this study also explore the influential factors that would affect the way of system integration, in the aspects of organization, strategy, policy and technology. This study concludes that four important factors, i.e., technical background and experience of the information and technology (IT) staff, institutional budget, data ownership, and new technologies, are critical in affecting how information systems get integrated in the government agencies. In the end, managerial implications and recommendations for future researches are provided. | en_US |
