Abstract

Integration of operational functions is an important issue in manufacturing management because the missynchronization of information on demand, planning, production implementation, and quality can reduce performance. This study aims to analyze the effect of cross-functional coordination on the integration of operational processes and operational performance in one of the manufacturing companies in Surabaya. The study used a mixed-method explanatory sequential based on synthetic data, involving 180 respondents, 12 key informants, 96 interview answers, and 72 operational observations for 24 months on three product families. Quantitative data were analyzed through correlation, operational data through KPI comparison, and thematic qualitative data. The results showed a positive relationship between coordination–integration (r=0.444), integration–performance (r=0.627), and coordination–performance (r=0.396). MAPE decreased from 10.51% to 8.20%, schedule adherence increased from 88.27% to 92.45%, and on-time delivery increased from 89.69% to 93.57%. Interviews emphasized the importance of information synchronization, decision coordination, and quality feedback. Findings show that cross-functional coordination strengthens process integration and supports improved operational performance.
