The number before the look
A feature that lets a number pass through a human hand does not ship, however convenient it looks. The number comes from the indicator and is recorded once stable; that comes before any layout or shortcut.
A system written to solve one problem, that kept working every day.
WeighHub was not written to be sold. It was written to fix one weighing problem: a reading copied from the indicator by hand, a ticket written on paper and then lost, and a month-end report assembled from scattered notebooks.
Nothing reaches a customer before it has been used in daily work beside the scale. What holds up there ships; what does not is removed before anyone sees it.
Once the system had settled in at its own site, it was offered to other companies that run a weighbridge, under the same rules it was written with on the first day: the number comes from the indicator, a correction is an addition rather than a replacement, and the record is read by whoever has the right to read it.
The system runs daily at a real production site, and every feature in it came from a real request.
