- Providing a vague answer about 'monitoring' without detailing specific detection methods.
- Jumping straight to proposing Cast AI features without understanding the customer's current setup.
- Not clearly explaining the data flow and how Cast AI achieves its insights.
- Focusing only on technical metrics without understanding business drivers or team responsibilities.
