The short answer
Separate functions become one enterprise system when shared journeys, one set of master data, clear system boundaries, and cross-functional decision governance are defined.
What keeps silos in place
Conflicting data ownership, manually assembled reports, and handoffs without owners between sales, operations, and finance.
A path to unification
Map end-to-end journeys → define sources of truth → design integration around state, not only interfaces → connect decision dashboards to the same definitions.
