A Study on the Factors Affecting the Korean Financial Institution’s Switching Intention to Open Source Software: Focused on System Software

This study aims to identify the factors influencing the intention of domestic financial institutions to switch from using proprietary system software to open source software (OSS). Based on the Technology, Organization, and Environment (TOE) Framework, this study categorizes technological, organizational, and environmental considerations as primary factors. Subsequently, subordinate factors were derived for each primary category, culminating in the construction of an Analytic Hierarchy Process (AHP) model to systematically evaluate their relative importance. Surveys were conducted among groups of internal and external IT experts within financial institutions, comparing and analyzing the results of factor weights between the two groups. It was found that internal IT experts placed higher weights on technological factors such as security, job suitability, and functional indifference, while external IT experts assigned higher weights to organizational factors like technological competency and cost advantage, along with job suitability of technological factors. This research highlights the differences in perception of the importance of factors between internal and external parties regarding transitioning to open source in the system software sector. Based on these findings, it is hoped that financial institutions will be provided with the environmental and institutional foundation to more actively participate in and contribute to open source projects.
