The situation
Orders arrived by email and were written onto a whiteboard in the planning office. Three spreadsheets sat behind it: one for the oven schedule, one for powder stock and one that reconciled the two.
The planner could not take a holiday. Twice a year the plant ran a batch in the wrong colour because the whiteboard and the spreadsheet disagreed, and nobody could say which had been right.
The work
We spent the first week of the quick scan on the floor, timing changeovers and watching how work really moved between the two oven lines.
Odoo Manufacturing with a work centre per oven line and capacity that reflects the real changeover time. Quality checks per batch, recorded at the line on a tablet. Inventory for powder stock, with reorder rules on the fifteen colours that move every week.
No customisation beyond two report layouts. The planning board is standard, and it is standard on purpose: it survives the next upgrade.
