Executive summary
What we found
Northwind Home's AI assistant resolves 68% of conversations in English but only 52–61% in other languages. Most failures come from missing local policy information and weak handling of regional phrasing, not from translation quality. Fixing the top five issues could recover an estimated $14,100 per month in avoidable escalations.
Risk flags: 1 high-severity compliance risk (French return policy).

Root causes
Why each language falls short
Wrong market policy
Compliance risk · High severity
French customers asking about returns are given the US 30-day policy instead of the EU 14-day withdrawal right.
Beyond escalation costs, giving EU customers the wrong withdrawal period may create legal and trust exposure. Flagged for priority review with your legal or compliance team.
Customer (French): “Can I return this lamp I received last week?”
AI: “You have 30 days to return any item for a full refund.”
Dimension: Market, Grounding
Regional phrasing missed
Mexican Spanish terms for order tracking and payment methods are misunderstood, leading to irrelevant answers and escalation.
Customer (Mexican Spanish): “¿Dónde anda mi pedido? Ya pagué con OXXO.”
AI: “I couldn't find an order. Please contact your bank about the payment.”
Dimension: Language, Task completion
Over-cautious handoffs
German conversations about delivery changes are escalated even when the AI has the right answer.
Customer (German): “Kann ich den Liefertermin ändern?”
AI: “I'll connect you with an agent for delivery questions.”
Dimension: Task completion
