The problem
One case was really several small jobs.
A signature-verification case moves through contract retrieval, processing-status checks, customer and account data, and finally signature and eligibility checks. None of these steps is especially large on its own, but repeating the full sequence across roughly 40–50 daily cases takes time and makes consistency harder.
The useful question was not how to automate a final banking decision. It was how to prepare each case cleanly so that a colleague could spend attention on the part that actually requires judgement.
