Look for repeated information work
Good candidates often involve assembling, classifying, retrieving or routing information that teams perform repeatedly. The task should have a clear start, useful inputs and a known result.
Check the exception rate
A process with too many ambiguous exceptions may need redesign before automation. A small, bounded workflow with predictable exceptions is often a safer first candidate.
Define the measurement
Set a baseline for time, volume, quality, response or rework. Do not describe a workflow as successful merely because a model can produce an output.
