Why does an internal AI trial need another review before customers use it?
Review an internal AI trial again before customers use it, because a customer service needs a different agreement about reliability, support and responsibility. Look at what changes outside the team and who runs the service after launch.
An internal test can be valuable even when it's incomplete. Moving to a customer service is a decision, and flipping an audience setting in a menu doesn't make it.
Think through the information the service receives and the promises people may infer. Add the route available when it can't help. Then check whether the test covered representative customer situations. Colleagues who know the intended answer may work around a confusing instruction that a new customer wouldn't understand.
Someone needs to review problems, maintain source material and decide when the service should pause. Make sure those duties have time and support behind them.
Keep the launch decision away from the excitement about the prototype. A successful experiment shows something worth examining, and it can't tell you the organization is ready to offer a service people will rely on.
