Interesting question. If you want to “practice” the FMEA, then I would consider the kinds of changes you would really like to make to a process (if time and money were not an issue), and then take one of the changes and conduct an FMEA on that change. That will give you practice. But you could also take one type of transaction with the customer, and brainstorm with other service personnel the kinds of things that can go wrong and then build preventive or contingency plans around them. Both would be good practice – and help you mitigate risk!
