Independent ERP comparison
Both can support enterprise requirements, but they fit into different technology ecosystems. Architecture, process fit and available skills should carry as much weight as features.

Dynamics 365 is particularly coherent in a Microsoft environment. Oracle Fusion deserves strong consideration when the organization wants a broad cloud enterprise suite or already has a strategic Oracle footprint.
