In an era where knowledge has become one of the most valuable assets, the ability to effectively gather, store, manage, and utilize knowledge is critical. Given the ever-changing market needs, the sustainable competitive advantage of a company is crucial. The aim of this research is to analyze the role of knowledge management capabilities in sustainable competitive advantage and to assess the effectiveness of the impact provided by knowledge sharing and the innovation value chain in enhancing a company's competitive advantage. The research method employed is quantitative research using a questionnaire with a 1 – 7-point Likert Scale for data collection. This study was conducted on employees, staff, and managers of a state-owned bank in Indonesia, with a sample size of 206 respondents. Data analysis will be performed using Structural Equation Modeling (SEM) technique with SmartPLS 4 software. The results of hypothesis testing indicate that the influence of knowledge management capabilities on knowledge sharing, and the innovation value chain is statistically significant. Furthermore, there is a statistically significant influence between knowledge sharing and sustainable competitive advantage, and knowledge sharing mediates the relationship between knowledge management capabilities and sustainable competitive advantage. The influence of the innovation value chain on sustainable competitive advantage is also significant, however, there is no significant evidence found that the innovation value chain mediates the relationship between knowledge management capabilities and sustainable competitive advantage.

Human resources that are of high quality create a competitive advantage for companies, thus Human Resource Management (HRM) and High-Performance Work Systems (HPWS) that are good become key success factors that need to be considered by every company. This study aims to investigate the influence of Human Resource Management (HRM) and High-Performance Work Systems (HPWS) on Information Technology (IT) Performance and Competitive Advantage of a company. The method used in this study is a quantitative approach with a questionnaire as the data collection method. The research sample consisted of 191 supervisors, managers, and executives of manufacturing companies located in Medan, Indonesia. Data analysis was conducted using SmartPLS 4.0 software. The results showed that Human Resource Management significantly affects IT Performance but does not directly affect Competitive Advantage. Meanwhile, HPWS Capability does not affect IT Performance but significantly affects Competitive Advantage. IT Performance significantly affects Competitive Advantage. IT Performance also mediates the relationship between Human Resource Management and Competitive Advantage. However, it is not significant in mediating the relationship between HPWS Capability and Competitive Advantage. These findings underscore that Human Resource Management (HRM) and High-Performance Work Systems (HPWS) play pivotal roles in shaping Information Technology (IT) performance and competitive advantage within companies, thus impacting the overall success and sustainability of companies.
