YOUR OBJECTIVE COMES FIRST
Legacy ERP dependency review
Change the system without losing the work it supports.
Michigan’s economic development corporation lists mobility, advanced manufacturing, engineering, life sciences, technology and professional services among its core industries. A useful scoping example is engineering changes across a supplier network. Follow a configuration change, supplier acknowledgement and production dependency through the work with engineering, supplier quality and program management. A change accepted by one supplier may leave another working from an older specification. How is acknowledgement tracked across every affected supplier?
Michigan Economic Development Corporation: 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 engineering changes across a supplier network, agree how engineering, supplier quality and program management 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.
