What problem does it address?
Disconnected systems create reconciliation work, reporting delays, and unclear ownership of customer and operational data.
Constraints to respect
Existing contracts and systems cannot be switched off immediately
Each system has custom fields and local processes
Users need access across entities without losing local context
Integration must be phased to manage operational change
What options should be on the table?
Consolidate everything onto one ERP
Build an API-first integration layer with a canonical data model
Centralize reporting in a data warehouse only
Integrate first, consolidate later
The recommended decision
Build an integration layer with a canonical data model first. Consolidate systems only where the business case is clear and the migration can be sequenced safely.
Outcomes to define and measure
A phased integration plan with clear data ownership and reversible steps. Platform consolidation remains a separate decision.
