Over the last two decades, pharmaceutical supply chains transformed dramatically. Acquisitions expanded product portfolios and geographic reach. Manufacturing became global. Contract manufacturers and external suppliers became critical. New therapies, evolving regulations, and rising service expectations created supply chains far more dynamic than before.

Along the way, organizations added technology to support growth: new ERP systems, legacy platforms that stayed in place, business-unit operating models, and regional variations. The result: one supply chain running across multiple disconnected ERP systems.

While each system still performs its original role well, planning across all of them has become increasingly difficult. Today's decisions must balance service levels, inventory, launch readiness, manufacturing constraints, compliance, customer commitments, and financial performance-and their consequences ripple across global networks.
