YOUR OBJECTIVE COMES FIRST
Legacy ERP dependency review
Change the system without losing the work it supports.
Alabama’s Department of Commerce identifies aerospace, automotive, bioscience, technology and operations and logistics among the state’s industry sectors. A useful scoping example is supplier engineering changes. Follow a part revision, customer specification and purchasing approval through the work with engineering, quality and procurement. A revised drawing can arrive after purchasing has already accepted the previous version. Which revision authorizes the next purchasing action?
Alabama Department of Commerce: industry context ↗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 supplier engineering changes, agree how engineering, quality and procurement 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.
