What can the factory actually make this week?

The plan lived in a spreadsheet and in one person's head.

Every week someone sat down with an order export, a stock report and what they knew about the factory, and worked out by hand what should be made. That knowledge was real and hard-won, but it only existed in one place, it took hours, and nothing behind it could be checked.

Moulds made it harder. Several products share the same mould, so two orders can quietly collide, and the only thing stopping that was somebody remembering. The question the business kept asking, and could never answer quickly, was simple: if we take this order, when can we actually make it?

A model of the factory, not another to-do list.

So we built one. Every product, every stage, every mould and every person is in there, with the real minutes each job takes and who is allowed to do it. Off that model, the app answers the questions that used to need a morning: what has to be made, who is going to make it, and what is going to be late.

It started as a capacity calculator. It is now the thing the week is planned on, and each round of real use adds the next bit of how the factory truly works.
