Using technology, such as human-machine interfaces, can enhance operational performance processes and increase the flexibility of the supply chain. Human-machine interfaces can produce operational control systems quickly and accurately. The research aims to explore the impact of human-machine interface on operational performance through collaborative decision making and supply chain agility. The sample criteria are the manufacturing companies with over 20 employees in Indonesia. The questionnaires were distributed offline (76 respondents) and online through Google Forms (427 respondents), so 503 questionnaires were valid—data processing using SmartPLS software version 4.0. The study results showed that the human-machine interface technology positively affects collaborative decision-making, supply chain flexibility, and operational performance with coefficients of 0,559, 0,490, and 0,340, respectively. Collaborative decision-making involving customer partners in planning decisions and communicating decisions with external partners influences supply chain flexibility by a coefficient of 0.375 and operational performance by 0.149. Moreover, supply chain flexibility with flexible planning and production processes and flexible labor placement influences operational performance by a coefficient of 0.381. The practical contribution of research enlightens company managers to build integrated systems and automation. It encourages top management and owners to think about investing in machines with high automation in the economy. Besides, these findings enrich the theoretical background in supply chain management and the resource-based view.

Products produced by manufacturing companies are always required to meet the requirements set by customers. Manufacturing companies need to maintain product quality by involving internal company components and external partners by using integrated information technology to become supply chain quality integration. All components in the supply chain flow must be committed to maintaining product quality in their respective roles. The research aims to ensure that technology information integration can impact firm performance through supply chain quality integration and resilience. Data collection on manufacturing companies in Java using purposive sampling found 162 companies that had received ISO certification. Respondents were determined to be employees at the middle management level and had worked for a minimum of 3 years. Data processing used partial least squares version 4 to answer all research hypotheses. The data processing results showed that information technology integration influenced supply chain quality integration by 0.588 and supply chain resilience by 0.523 and had no significant effect on increasing firm performance. Supply chain quality integration influences supply chain resilience by 0.288 and increases firm performance by 0.496. Lastly, Supply chain resilience has a positive and significant effect on increasing firm performance by 0.169. The research results provide a practical contribution to the company's top management in maintaining the role and function of technology information integration and the ISO system in maintaining supply chain quality integration. Theoretical contribution to enrich the theory of total quality management and supply chain management.
