Build the CI relationship structure (store → device parent relationships) for all SGC-discovered CIs using Dependency Views and relationship types

Develop scheduled CMDB completeness report script — querying CI fields and writing completeness scores to Performance Analytics for governance dashboard

HAMPRO Configuration

Configure HAMPRO model records for all hardware types

Set up warranty tracking, EOL date fields and automated warranty expiry alerts (90-day, 30-day pre-expiry notifications)

Build Flow Designer workflow for device replacement RITM: procurement request creation, shipping tracking, device provisioning steps, monitoring onboarding checklist and retired asset decommission

Configure HAMPRO financial fields — purchase cost, depreciation schedule, book value — for retail hardware asset records
