Organizational adoption of information technology is an important decision for modern enterprises. Proper use of technology can increase benefits and competitive advantage. Inappropriate use could cause failure. Most previous literature focuses on treating technology adoption as a rational decision based on the functional needs of an organization. In many cases, however, technology adoption is not due to functional needs but environmental or peer pressure (called symbolic or ceremonial adoption). Different motivations for adoption may lead to different outcome. In addition, there is no generally accepted organizational adoption model that can include all key factors into consideration. Therefore, this study tries to understand what factors will affect an organization¡¦s adoption of a new information technology or use an information technology and whether different purposes (intangible value vs. tangible value) will affect the adoption or usage of information technology in organizations. The framework of this study was extended from the Fit-Viability Model to include the internal organizational factors and external environmental factors. We conducted a survey study and use PLS to analyze the collected data. The results show that the extended FV model can interpret organizational IT adoption and IT usage. The purpose of adoption did have effect on the intention to adopt information technology. In the symbolic adoption situation, TEF and viability had significant impacts on organizational intention to adopt; and in the functional adoption situation, TTF and viability had significant impacts on organizational intention to adopt. Different purposes of adoption have less significant effect on the actual use and performance of information system. TTF and actual use had significant impacts on organizational performance, and viability also had significant impacts on actual use of information technology in both situations. In other words, organizations can also benefit from IT adoption even if the original motivation was symbolic.

The increased popularity in mobile devices and technology has motivated business to adopt the technology for increased productivity. However, not much research has investigated the adoption of mobile technology. The purpose of this thesis is to study the factors that influence the adoption of mobile technology and to develop a model of mobile technology adoption. The model can serve as a foundation for future research and provide useful guidelines for organizations that plan to adopting mobile technology. The model suggests two categories of factors that determine the decision of adopting mobile technology: fit and viability. Fit measures whether the functional capabilities of mobile technology match the need of a task, whereas viability measures whether an organization is ready for the technology. This research develops instruments for measuring fit and viability. A survey was conducted to collect data for model evaluation. Major findings from the study include: (1) the fitness between task and technology had a direct positive impact on the success of mobile system adoption. (2) Personal characteristic and organizational viability had indirect positive impacts on the success of mobile system adoption via the mediation of system quality. (3) Personal characteristic and organizational viability had positive impacts on the information quality and system quality but had no impact to the service quality. (4) Only the system quality had a positive impact on the success of mobile system adoption.

The main goal of this study is to understand factors in implementations of mobile guide systems in exhibitions and to discuss how ¡§ fit¡§ and ¡§viability¡§ perspectives affect the wiliness of exhibitors to implement mobile guide systems. The study begins with interviews with Professor Hong Wanlong and Mr. Zhangjian Zhiting of National Science and Technology Museum, to understand how exhibitors evaluate mobile guide systems. Combined with analysis and induction of perspectives and variables from studies of past journals, sub-perspectives of ¡§ fit¡§and ¡§viability¡§ are built. Then, for a through statistical survey, a questionnaire survey is conducted to explore the wiliness of exhibitors to implement mobile guide systems. Analysis revealed that localization, sufficient storage for databases, mobility and timeliness showed positive correlations between the ¡§ fit¡§ perspective, while financial concern, infrastructure of information technology, support from top management and capability of information technology department showed their positive correlations with the ¡§viability¡§ perspective. However, the ¡§financial concern¡¨ factor showed a lower significance level than others, indicating that for exhibitors the factor is taken into account but not the most important concern.
