Rules or AI: which should you automate first?

Does your team copy details from WhatsApp to a spreadsheet and then into another system? Before adding AI, ask which parts follow a rule and which need judgment.

A fixed rule can check that an enquiry has a name, a way to reply and the right service. It can store the request once, spot an exact duplicate and alert a person when a field is missing. The rule should be written down and tested. A failed integration must not turn a blank field into an invented answer.

AI can help where the input is less tidy. It may summarise a long message or suggest whether it concerns an order, a complaint or a general question. Its suggestion is not the business's final answer. If the message changes a price, promises a deadline, accepts a contract or sends a sensitive reply, a person should decide.

Try three enquiries. The first has every required detail: the system records it and shows what happened. The second is identical: it points to the first record rather than opening another job. The third says, "Can you do something special for Saturday?": it reaches a person with the original wording intact. Those paths should be visible in a test, not hidden behind a reassuring demo.

A simple decision map helps:

• Clear input and approved rule: automate it and log the result.
• Free text that needs interpretation: prepare a suggestion with its source and confidence limits; ask for review where the stakes are high.
• Price, payment, exception or promise to a customer: stop for the named human decision-maker.

This is not a contest between rules and AI. Rules can be stale or wrong too. Check that the source is current, define who can change it and rehearse the failure paths. Then measure the hours spent before and after, including maintenance and corrections. A task is not "saved time" if someone spends that time fixing false alerts.

Start with one process you repeat each week. Write down its input, rule, exception and responsible person. If those four parts are unclear, simplify the work before you automate it.

The examples in this note are illustrative, drawn from common small-business workflows.
