Supply chain touches more data streams than any other healthcare organization function, making modernization complex and high stakes. In this session, HSHS and Quorum Health reflect on their successfully completed, large-scale cloud ERP migrations within the past 6 months, sharing the decisions and preparations that mattered most. Despite data complexity, operational demands and steep learning curves, both organizations maintained continuity. HSHS sustained an exception rate under 2% during implementation, which is a testament to their attention to detail and commitment to accuracy. Attendees will gain insight into how thoughtful planning and data discipline support successful transformation without disrupting performance.
