Begin with recurring work that has clear inputs, predictable decisions, and a visible result. Enquiry routing, appointment reminders, document collection, approval notifications, and routine reporting are usually strong candidates.
The goal is not to remove people from the process. It is to remove repeated copying, waiting, and chasing so the team can focus on judgement and customer care.
Choose one workflow, record the current time and error rate, then compare the result after launch. Useful automation should make the improvement obvious.
