8 · Reliability and a fallback for when AI is wrong
Here's the rule that separates safe automation from a disaster: AI will sometimes be wrong, so you design for that before it happens — not after. A model can confidently invent an answer, mis-read a form, or break when something unexpected shows up. An automation that assumes AI is always right is a trap waiting to spring on a customer.
Build reliability in from the start:
- Keep AI out of the high-stakes path on its own. Anything involving money, legal commitments, or a promise to a customer gets a human check before it goes out. NIST's framework calls trustworthy AI "valid and reliable," and you get there by putting human oversight around the model, not by trusting it (NIST, 2023).
- Set confidence limits. When a tool isn't sure — an unusual question, a low-confidence match — route it to a human instead of guessing.
- Test on real cases before going live. Run your automation against real (or realistic) examples and watch where it stumbles.
Always have a fallback — a plan B for when the automation fails:
- A human handoff path that actually works (Lesson 4), not a dead end.
- A manual version of the process you can run if the tool goes down. If your whole ops grind to a halt because one app is offline, that's a fragile business.
- Monitoring — check your automations regularly. "Set it and forget it" becomes "set it and it's been emailing customers garbage for a week and nobody noticed."
The accountability part: NIST is explicit that trustworthy AI is accountable and transparent — a person is answerable for what the system does (NIST, 2023). "The automation did it" is never an excuse a customer (or a regulator) accepts. You own the output, so you build the safety net.
Check yourself. What does "design for AI being wrong before it happens" look like in practice? Name one reliability check and one fallback you'd put on a customer-facing automation.
