Write-back is where the risk is, and it is also where most of the value isn't. Start with an agent that tells people what to look at.
Every agent conversation with an enterprise eventually reaches the moment where someone says "and then it creates the purchase order." That is the moment to stop and ask whether the agent needs to.
In the supply-chain work we have shipped this year, our agents recommend. The shortage agent ranks which shortages matter today; the supplier-messaging agent drafts the supplier email. A human creates the PO, a human clicks send. Nobody on the business side has asked for that to change, and the security review was a fraction of what a write-back agent would have needed.
It is not enough to say the agent doesn't write. The agent should also not recompute. If SAP already carries a running balance, read it; do not sum the elements again and hope you land on the same number. When the two disagree, the system of record wins, and the disagreement is a defect to fix, not a feature to explain.
Stamp every row with the date the data was extracted. "You are short 4,200 units" is a different sentence from "as of Tuesday's extract, you were short 4,200 units", and only the second one survives a planner checking it against the screen on Wednesday.
Add an action when the pilot users are asking for it and the action is small, logged, and reversible — creating a draft email in the buyer's own mailbox, for instance, rather than sending it. Draft-first is a good second step because the human click is still the approval gate.
Tell us what system the answer lives in and who needs it. We'll reply with a view on whether it's a two-week assessment, a five-week pilot, or something else.
