This invention introduces systems and methods that control production
process quality, wherein the production process has a plurality of
durable items, each durable item is associated with a re-qualification
process initiated as a function of a life expectancy associated
therewith. The life expectancy associated with each durable item is reset
upon completion of the associated re-qualification process. An exemplary
method comprises (I) monitoring re-qualification indicia associated with
each associated re-qualification process, and (ii) controlling
availability of re-qualified durable items of the production process as a
function of the re-qualification indicia to thereby control production
process quality.
