Thus, this study investigates the effects of two entrepreneurial characteristics (innovativeness and risk taking) on two software characteristics (innovativeness and standardization) which lead to software flexibility and performance. This study also examines the moderating role of the regulatory environment in the relationships between entrepreneur and SW characteristics. Data from 257 domestic Korean software firms were collected from a random sample. The structural equation model was formed using AMOS 19.0 to test the proposed hypotheses. The results indicate that the two entrepreneur variables had positive effects on SW characteristics which in turn had a positive effect on software flexibility and performance. Moreover, the regulatory environment had positive effects as a moderator between entrepreneurial and software characteristics.
