Buyers should also think about how the order will be consumed after delivery. If one heat or lot will be divided across multiple parts, workstations, or shipments, the traceability plan must be simple enough for production teams to follow. This is where a supplier’s real competence becomes visible. Good control makes the material ordinary to use, even when the application is technically demanding. Poor control makes every later review harder than it needed to be.<\/p>\n
