Analysis of the Impact of Information Technology Implementation on Company Performance using the Tobin’s Q Approach

This study aims to analyze the impact of information technology implementation on corporate performance using the Tobin's Q ratio approach. In the current digital era, information technology has become a strategic factor in enhancing operational efficiency, competitiveness, and corporate value. This research employs a qualitative method with a case study approach involving two companies in Medan City, namely PT Bank Pembangunan Daerah Sumatera Utara (Bank Sumut) and PDAM Tirtanadi. Data were collected through document analysis, semi-structured interviews, and digital observations, supported by financial reports, Google Trends digital data, and official company publications.The findings indicate that the implementation of information technology has a positive impact on corporate performance, as reflected in the Tobin’s Q value, which shows an upward trend in line with the digitalization of services and operational systems. The analysis of digital trends in Medan also reveals a growing interest in business digitalization and digital transformation in the post-COVID-19 period, although it remains below the national average. The implications of this research suggest that companies in Medan have significant opportunities to improve market value and operational efficiency through the adoption of information technology, provided that human resource readiness and appropriate implementation strategies are prioritized. Theoretically, this study contributes to the literature on the relationship between information technology and corporate performance in Indonesia, particularly in regions outside of Java Island.
