The purpose of this research is to present the major factors which determine dominant design of Smartphone OS and to verify a logical causal relationship with them and user satisfaction. To achieve this goal, OS compatibility, OS enhancement, Installed base, and network effect were presented as determinants of Smartphone OS which serves as the basis for determining dominant design and their logical causal relationship with user satisfaction was empirically analyzed. The results of the research showed that OS compatibility and OS enhancements had a positive effect on the expansion of user base. Of the two factors, OS enhancement showed that it does not only expand the user base but also acts as the cause for the fortification of the network effect. Furthermore, it was shown that OS enhancement had a direct positive effect on user satisfaction. The findings of this research are significant in its academic contribution as well as its potential for practical application by presenting the logical causal relationship in the process of determining OS dominant design an area which was previously untouched by empirical testing.

The purpose of this research is to look upon the smartphone market from the perspective of business ecosystems and to extract the critical success factors of OS platforms. Furthermore, this research aims to verify the effect of those factors on increasing utility resulting from the rising number of users as well as on intention of use. In order to do this, OS compatibility and OS upgradability were presented as the major characteristics of OS platforms and a logical causal relationship between network effect and intention to use which shows the increase of utility according to the number of users was established which was then followed by an empirical analysis. The results of the research showed that OS compatibility and OS upgradability both had positive effects on network effect and intention to use. By presenting the characteristics of OS platforms, a subject which has lacked pervious empirical studies, and establishing a logical causal relationship for the role platform characteristics play in the formation of business ecosystem in the smartphone market, it is expected that the findings of this research will contribute greatly not only academically but also in practical applications.
