The foundation every other stewardship practice rests on. DR can't restore what isn't inventoried; vendor vetting can't bound data flows it doesn't track; IR can't scope a breach to systems it doesn't know exist.
Hard finding · No documented inventory
Without a documented inventory of student-data systems, DR scope, vendor vetting, and incident response all operate on assumption rather than fact. This is the foundational stewardship gap — resolve it before tightening downstream practice.
Each system in the inventory mapped to a named IT owner and a backup/recovery tier (Tier 1 hot · Tier 2 nightly · Tier 3 archive). The bridge between stewardship inventory and DR planning — cross-references Data Resiliency for backup posture detail.
Inventory reviewed and refreshed at least annually. School-year rhythm makes summer-into-fall a natural cadence. Stale inventory means stale DR scope, stale vendor list, stale parent-disclosure surface.
