Follow the work before naming the solution.
This is where the listening happens. We talk to the people doing and receiving the work. We read real examples, especially the awkward ones nobody puts in the demo. We trace the sources, the approvals, the exceptions, the rework, the handoffs, until we can say what the workflow is actually for and which rule it must preserve. Only then do we let anyone, ourselves included, say the word "agent."
An illustration, not a client case
A support-summary project, for example, is never only a summarization problem. The questions that decide whether it works are questions about the business: which source wins when the records disagree, what must be quoted rather than paraphrased, which issue always escalates to a person, and whether anyone downstream will act on the summary at all. A better model cannot answer those. Somebody who listened can.
