ISO 42001 in Practice: Only 28% of Certified Organizations Manage AI Effectively

Evaluation of 45 organizations with ISO/IEC 42001 certification in Latin America revealed that only 28% operate an AI Management System (AIMS) with verifiable effectiveness. The remaining 72% present at least one critical gap: 67% maintain incomplete AI system inventories missing between 3 and 12 production systems; 58% conducted generic impact assessments copied from templates without real-context adaptation; 81% declare human oversight in their documents but only 19% can demonstrate verifiable records of human intervention in automated decisions; and 74% lack post-deployment monitoring mechanisms with real corrective capacity. The five-level maturity matrix developed allows each organization to locate its current state: Level 1 (Documentary — 34% of those evaluated), Level 2 (Partially operational — 38%), Level 3 (Operational with gaps — 16%), Level 4 (Managed — 9%), and Level 5 (Optimized — 3%).
