Why do plants still plan production in spreadsheets?
Because sales, purchasing, stores and production each keep their own records, and none of them agree. The order book sits in one file, stock in another, and the schedule on a whiteboard. Manufacturing ERP software puts them on one set of data, so a new order, a late PO or a short receipt shows up in the plan straight away.
Each product in the suite covers one step from order to shipment. Together they pass the same order lines, parts and stock from one team to the next, with no re-keying in between.
