Hey Guys,

Does anyone have recommendations about how often product audits should be done? I'm thinking it should be based on the frequency of product return. Thanks!

Product return is certainly one consideration, since it let's you know (with some uncertainty) how often defective product is being shipped.  However, you might also want to consider 1) the ability of a product audit to detect the problem (inspection is not 100% effective), 2) the cost of product audits, 3) the cost and potential customer loss impact when defective product escapes, and 4) other risk considerations.
Duke makes great points.  But if you want this to truly be an audit, it can be treated as such.   You can create a schedule and then sample products across different strata.   The product audit sample can be selected across different product lines, different customers, different manufacturing processes, shifts, etc.

Thanks guys. We really only do product audits when there are returns now, but the problem is we get multiple returns for the same products sometimes. I'm thinking maybe the threshold for the audit should be returns per quarter. If we get multiple returns per quarter on one product, we should audit that product on a monthly basis.

So you may want to consider doing some pre-shipment audits, and/or some process audits that focus on the controls that have failed to prevent the defects in returned products.
