Business challenge
Performance reporting needs governed joins, shared measures, time definitions, and access rules.
Migration approach
Assess logical and presentation layers; propose reviewed LookML models, views, and dashboard requirements.
Deterministic work
Apply approved mappings and checks to the supported report and semantic definitions. Record rule versions, target constraints, and unresolved exceptions; verify outputs against an agreed baseline.
Agentic assistance
Use permitted context to explain calculations, propose mappings, identify gaps, and prepare review questions. Review generated proposals before adopting them as implementation or access rules.
Acceptance evidence
Compare target queries, aggregation behavior, time dimensions, access filtering, and agreed measures.
Delivery time
The 34 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.
