Hello,
As a means of reducing our on-hand inventory, a vendor of ours keeps a just-in-time inventory of various items in their US warehouse after it is built overseas. While this is beneficial for us in terms of space, it means that currently we might receive 20 incoming lots of 50 pieces rather than just receiving 1000 pieces at one time. Overall this increases our QC Inspection time due to the non-linear relationship betweeen sample:lot size and the paperwork that must be completed each time. Since we know what the overall lot size is and since the product is built to our specification, I am wondering if there is any reason why we couldn't perform our sampling based on the overall lot size when the first shipment (or two or three) arrive, then disregard sampling on all subsequent mini-lots from the same master lot until a new lot is built. I know this would require careful bookkeeping in order to ensure that new lots are flagged, but I suspect it would save time in the long run. To be honest, this idea was suggested to me and I am quite hesitant to try it, but don't necessarily know why.
In case it helps, we are sampling using the ANSI Z1-4 plan and our inspections consist of attributes and variables (wire length, wire continuity, etc.) The vendor's quality system is ISO 9001.
Thanks in advance,
Bob
