Every demo is a magic trick performed with the magician's own props. Describe your workflow and this builds ten ugly, real-world cases to throw at a tool, yours or a vendor's, so you see where it breaks before your optimism makes that break expensive.
Use fake or anonymized examples. This tool invents ugly test cases; do not paste real customer data.
