Why it matters
What I see behind almost every digital banking story is the same tension: the front end is modern and the core is still a system that has been running for twenty years and nobody dares touch. The distance between those two layers explains most of the projects that slip.
I read these stories with two questions on top: what happens to cost per transaction and what happens to risk. If cost drops but risk rises without anybody measuring it, the saving is borrowed and gets repaid with interest on the day of the first incident.
What usually goes wrong
The mistake that repeats is testing only the happy path. It gets validated that the transaction works, not that the reversal works, that duplicates are caught, that a power cut mid-operation leaves everything consistent. Those cases are ninety per cent of the real work and ten per cent of the testing.
What to watch
- How money is returned when something fails, and how fast the customer sees it.
- Which part of the customer relationship ends up with a third party and whether that is reversible.
- What happens to cost per transaction at real volume, which is where the business is decided.
How I read this entry
What I would ask for before approving something like this is the plan for when it fails: how the customer gets their money back, in what timeframe, who authorises it and what they are told meanwhile. In payments, the quality of the recovery matters more than the quality of the happy path.
The original story is published in another language; the excerpt is quoted as the publisher delivers it and the commentary is written in English.
