This is a case-study blueprint; no deployment results or customer endorsement are claimed.
Business challenge
Sources use different product, supplier, location, status, currency, or unit codes.
Migration approach
Apply governed code crosswalks, canonical identifiers, compatibility checks, and effective-date rules. Propose alignments and identify unmapped or conflicting meanings for owner review.
Deterministic work
Apply governed code crosswalks, canonical identifiers, compatibility checks, and effective-date rules. Record rule versions, target constraints, and unresolved exceptions; verify outputs against an agreed baseline.
Agentic assistance
Propose alignments and identify unmapped or conflicting meanings for owner review. Review generated proposals before adopting them as implementation or access rules.
Acceptance evidence
Validate mapping coverage, unknown-code behavior, relationships, historical applicability, and stewardship sign-off.
Delivery time
The 13 months (estimated) assumes the stated migration inventory, accessible source definitions, available reviewers, and an agreed target environment. Plan discovery, design, build, parity testing, business review, and release readiness as separate checkpoints. Re-estimate when access, custom features, data issues, or acceptance scope changes.
