Why This Book?
ERP Reimplementation Is More Than Software
An ERP reimplementation is an opportunity to rethink how the organization operates—not simply reproduce the existing environment in a new configuration.
The Oracle NetSuite Reimplementation Playbook provides a practical framework for IT Program Managers responsible for leading an ERP transformation from planning and discovery through design, integration, testing, go-live, and continuous improvement.
The focus is on building a simpler, more integrated, more scalable ERP environment while avoiding unnecessary customization and complexity.
