Lot based QA

The basic principal is that each part of the physical works (and / or each process) is included in one of a number of lots which are recorded on a lot register. All of the testing, inspection, conformance checks and valuation of work completed is referenced back to the lot which contains the work in question. The records associated with each lot are compiled and managed as a separable record of completed work.

What comprises a lot is relatively simple and is explained in the section "What is a lot?"
