RPA, AI, or both? Choosing the right automation for the job
"Should we use RPA or AI?" is one of the most common questions I'm asked, and it's usually the wrong question. The two aren't competitors — they're tools for different kinds of work. Reaching for the wrong one is an expensive way to find that out.
What each is actually good at
Robotic Process Automation (RPA) is brilliant at rules-based, repetitive, high-volume work. If a task follows the same deterministic steps every time — rekey this field, reconcile these two reports, move that file — RPA does it tirelessly and accurately. It struggles the moment the work requires judgement or the inputs are messy.
AI earns its place where there's variation, language or judgement. Reading an unstructured email and classifying it, summarising a case file, drafting a first-response letter, spotting an anomaly — these need interpretation, not just repetition. AI handles ambiguity that would break a rules engine.
The simplest test: if you can write the rules down completely, it's an RPA job. If you find yourself writing "it depends," that's where AI comes in.
The two belong together
The most effective automations I've designed use both. AI does the reading and the judging at the messy edges — interpreting a request, extracting the right data, deciding the path — and RPA does the reliable, auditable execution in the systems of record. AI for the thinking, RPA for the doing.
Don't automate the mess
Whichever you choose, the prerequisite is the same: you have to understand the process first. Automating a broken or undefined process just produces wrong outcomes faster — and with a bot's enthusiasm. A mapped, governed process tells you three things you can't guess at:
- Where the volume and cost actually sit — so you automate what pays back, not what's merely visible.
- Which steps are rules and which need judgement — so you pick the right tool for each.
- What "good" looks like — so you can prove the automation is behaving, not just running.
The honest answer
So — RPA or AI? Usually the answer is "map it first, then probably both, in the right places." Get the process baseline right and the technology choice becomes obvious. Skip it, and you're buying tools in the hope they'll impose an order you never defined.
