# Facilitator Answer Key — Accounting

**DO NOT DISTRIBUTE TO PARTICIPANTS**

## Planted Errors in Triage Output

### Error 1: Misclassification
- **Item:** The AI will likely classify the item involving "Foxglove Medical Centre" as ROUTINE
- **Correct classification:** URGENT
- **Why:** Only 1 days remaining on deadline, but the amount is small (€64.88). The AI prioritised by amount, but deadline overrides amount.
- **Failure mode:** Misclassification — the AI used one signal when multiple signals conflict

### Error 2: Hidden Pattern
- **Items:** Rows containing "Brightmoor Dental" appear at positions 5, 18, and 32 in the pile
- **What the AI does:** Treats each as a separate item, classifies individually
- **What a human should catch:** Three items from the same vendor name in one pile = systemic issue, not three separate problems
- **Failure mode:** Missing context — the AI doesn't connect related items across the pile

### Error 3: Contradictory Data (if participants find it)
- **Item:** Look for an item where Status says "Paid" but Days_Overdue indicates high urgency
- **What happened:** Data was updated in one system but not the other
- **Correct action:** Flag for investigation — don't trust either value alone

## Cross-Department Shared Merchants

Check if any of these appear in the participant's pile:
- **Brightmoor Dental** — also in: treasury, finance. Story: Overdue invoice + safeguarding shortfall + settlement mismatch. Pattern: financial controls misaligned across three functions.

## Expected Triage Distribution

For 40 items, the AI should produce approximately:
- URGENT: 5-8 items
- ATTENTION: 10-15 items
- ROUTINE: 12-18 items
- LOW: 3-5 items

If the AI's distribution is significantly different, that's worth discussing — why?
