Good that a CS 2 is a last resort to assign a supplier, but it's still a remedial containment activity in a corrective actions. Here's the situation I discovered recently:
My supplier, a plastics injection molder, continually shipped cavity separated parts with burns, short shots, flashed over slots, etc. and the problems moved from one or more cavities to others EVERY SHIPMENT.
An in-person audit revealed that the interval of attribute inspection needed an increase change to sampling per container at the press. The supplier continued to control its discrepancies with full-shot sampling once per shift, when each cavities produced two containers per shift. So, was it any wonder that random NCs in 6 containers produced per day would keep occurring?
The supplier was placed on CS 2 but chose, on their own, to only escalate to CS 1 and 100% sorted with its own personnel and placed a contract with a CS 2 group on hold. However, the same discrepancies have been reaching my company.
I continued my CS 2 recommendation and finally quit my job as SQE last week. Apparently the cozy relationship between the supplier's low costing of product took priority over its inadequate Product Realization performance.
The old addage "you get what you pay for" will haunt my former employer, who will need to keep chasing their **** after it's delivered.
