Problem Statement: IT Asset Management

How Problem Statement: IT Asset Management (understanding) informs IT Asset Management architecture and interviewer depth.

Problem Statement: IT Asset Management

Enterprise ITAM is a custody ledger over hardware, software entitlements, and financial attributes—not a spreadsheet with barcodes. ServiceNow and Snipe-IT win when every laptop, license seat, and disposal certificate shares one asset_id, monotonic custody_version, and append-only audit suitable for SOX.

Problem Statement: IT Asset Management — design checkpoint (understanding)

Quote SLOs aloud: asset register write P99 < 150ms, assignment checkout P99 < 200ms, discovery normalize lag P95 < 5min, physical audit match rate > 99.9%, orphaned custody rate < 0.05%.

ServiceNow-class ITAM fails when discovery overwrites custody without merge policy—bind mutations to asset_id + monotonic custody_version.

Track receive RPS, open custody transfers, discovery backlog, and audit mismatch rate during understanding.
