YOUR OBJECTIVE COMES FIRST
Legacy ERP dependency review
Change the system without losing the work it supports.
Rhode Island Commerce highlights the ocean economy, custom manufacturing, life sciences, IT and business services. A useful scoping example is design-to-production customer changes. Follow a design revision, customer approval and production instruction through the work with design, account management and production coordination. An informal customer comment must not silently replace an approved production specification. What turns a requested design change into an authorized production instruction?
Rhode Island Commerce: Industries ↗01Inventory the dependencies people rely on
Map the application, scheduled work, interfaces, reports and users affected by the proposed change. Identify undocumented file exchanges and manual workarounds. Ask the operating team which output would be missed first if a dependency stopped.
02Choose a migration boundary
Compare upgrading, isolating a component, changing infrastructure and replacing an application. Define the data and behavior that must remain consistent. A smaller boundary can make testing and recovery more understandable than moving every dependency at once. Working example: A dependency register and reconciliation checklist.
03Rehearse reconciliation and recovery
Use a representative copy to test data migration, permissions and key transactions. Agree checks that explain whether the target is correct and a recovery decision point. A backup is necessary preparation, but the release plan also needs a workable restoration or rollback path. For design-to-production customer changes, agree how design, account management and production coordination contribute where those functions are involved.
04Leave an operating model behind
Agree responsibility for access, deployments, monitoring, costs and support. Document how environments differ and how changes are approved. Modern infrastructure is only useful when the responsible team can understand and maintain it after the handover. Review check: Owners can reconcile the outputs needed for the next operating cycle.
