The useful question is not “where can we add AI?” It is “which part of this workflow benefits from judgement under uncertainty?”
Short answer: use ordinary rules when the input and correct output are known. Use AI for bounded tasks involving language, classification, extraction or search when a person can review the result. Keep accountable humans responsible for consequential customer, financial, legal, medical and professional decisions.
Use rules when certainty is available
If an order total exceeds a threshold, route it for approval. If a form is incomplete, request the missing field. If a payment is overdue by seven days, create a follow-up task. These are deterministic rules: the same input should produce the same output.
Adding a language model would make those steps slower, more expensive and less predictable. Ordinary automation wins.
Use AI when interpretation has value
AI becomes useful when information is unstructured and several reasonable outputs may exist. Examples include:
- extracting fields from varied supplier documents;
- classifying enquiries before a person reviews them;
- drafting a reply using approved business information;
- searching policies or product knowledge expressed in natural language;
- summarising a long case history for an accountable professional.
The model is assisting interpretation. It is not silently becoming the owner of the decision.
Start where mistakes are cheap, visible and reversible
A first-pass draft that a person reviews is bounded. An incorrect automatic refund, diagnosis or contractual commitment is consequential. The best first AI workflow usually has a clear reviewer, an obvious source of truth and a safe fallback when confidence is low.
Ask three questions: who notices an error, how quickly can it be corrected, and what happens before it is corrected? If the answers are unclear, narrow the task.
Control the data path
Map what information enters the system, which provider processes it, what is stored, who can retrieve it and how long it remains. Minimise what is sent. Avoid putting sensitive data into a model merely because it might be useful later.
Retrieval systems should show sources where practical. Logs should record enough context to investigate failures without becoming an unnecessary archive of sensitive information.
Measure the business outcome
“We launched an AI assistant” is not an outcome. Measure review time, correction rate, queue length, response time or successful self-service. Include the human checking effort and the cost of exceptions.
A simple rule that removes eighty percent of manual work is better than an impressive AI demonstration that creates a new checking burden.
A sensible first pilot
- Choose one repetitive, reviewable task.
- Collect representative examples, including difficult ones.
- Define acceptable output and unacceptable failure.
- Keep a person in the loop.
- Measure corrections as well as time saved.
- Expand only when the evidence supports it.
