Traditional automation is deterministic. It executes a predefined sequence: when this happens, do that. It is fast, cheap, and reliable — as long as the inputs are structured and the path is predictable.
AI automation is probabilistic. It interprets unstructured input — a phone call, a scanned invoice, a vague email — and determines intent before acting.
How to choose
- Structured input, fixed path: use traditional automation.
- Unstructured input or judgment required: use AI.
- High volume with frequent exceptions: combine both — AI interprets, rules execute.
The practical architecture
The most durable implementations use AI at the edges, where the world is messy, and deterministic workflows in the middle, where accuracy and auditability matter. That pattern keeps outcomes measurable and keeps AI out of decisions it should not own.
