The organization has a project manager responsible for all procurement and projects. The criteria of suppliers or vendors are those who have paid taxes, have a taxpayer number, and have an adequate bank account. Data analysis used the SEM-PLS approach employing SmartPLS software version 4.0. The data processing results showed that project management capability positively affected information technology integration by 0.712, supply coordination by 0.432, and process innovation by 0.250. Information technology integration positively impacted supply coordination by 0.445, process innovation by 0.254, and organizational performance by 0.304. Supply coordination positively affected process innovation by 0.366 and organizational performance by 0.385. Finally, process innovation had a positive effect on organizational performance by 0.234. The research provides insights for foundations to optimize the role of departments in building supply coordination using information technology. Project managers must optimize integrated information technology by maintaining investment and upgrading equipment, making a theoretical contribution to supply chain enrichment, and using a resource-based view.
