Four steps of an agent working a refund ticket, each drawn as the stack of messages it re-reads plus the one it writes. Step 1 reads the task, refund #4411 if damaged, and writes photos: the box is damaged. Step 2 re-reads both and writes refund issued, with a tick, in red, noted it wasn’t. Step 3 re-reads all three, the wrong one included, and writes so: close the ticket, noted it shouldn’t. Step 4 re-reads all four and writes email: refund’s on its way!, marked with a red cross and noted it’s not. Underneath: compounding mistakes.
