Manufacturing Quality: Variation Picked the Wrong Person Hats

Manufacturing quality has two different sets of boundaries: NIST distinguishes control limits, which assess process stability, from specification limits, which concern intended product function. ASQ separates common-cause variation inherent in a process from special causes that indicate a loss of statistical control. These hats give that careful distinction an unreasonable amount of personal confidence. QUALITY CONTROL and QUALITY ENGINEER are the straightforward badges. STATISTICAL CONTROL FREAK turns the process vocabulary into a personality claim, while I AM THE CORRECTIVE ACTION promotes the wearer from investigator to solution. The latter already appears on QA/QC apparel, alongside the inspector phrase TRUST BUT VERIFY. Here, the approval stamp, the first article and the out-of-spec part each get their own joke. Acceptance sampling uses a random sample to decide what happens to a lot; NIST identifies acceptance as its principal purpose, rather than estimating the lot's quality. First-article work has its own formal documentation: IAQG's 9102 standard addresses aviation, space and defense applications. Those specific practices supply the setting for the collection's exaggerated authority. Choose a plain role badge, a koala pun or an art-gallery defense of the reject pile, with two colorways each for STATISTICAL CONTROL FREAK and I AM THE CORRECTIVE ACTION.
