Skip-lot sampling

This post was sent in by Susan Young:    We are an OEM Mfg. that has 100$% inspection. We put a dock to stock in place and when it didn't take off,  we pulled the procedure from our master document list. I believe dock to stock is an outdated tool and I would like to understand best practice of skip lot so that possibly we could get some parts through the process quicker.

The Statistics Division has an ebook on Skip Lot Sampling available for $15 through ASQ Press, part of our How To Series:
#4 How to Perform Skip-Lot and Chain Sampling, 2nd Edition, by Kenneth S. Stephens

Another good reference is the NIST Engineering Statistics Handbook, which briefly outlines the process here.
