Shop-Floor and Inspection PCs: Change Control

Owner Dana Whitfield · updated 2026-05-05

CMM, CNC programming and inspection PCs are under change control (QP-7.1.5). Windows updates are deferred and installed in a scheduled window with Quality sign-off. No software installs or admin rights without a Quality-approved change.

Why

CMM and inspection PCs produce records for customer first-article inspections (WI-210). Uncontrolled changes can invalidate a measurement program.

Rules

  • Windows updates on CMM PCs are deferred and installed on the first Saturday of the month after Quality sign-off.
  • If a restart prompt appears during a measurement run, postpone it; do not restart mid-program. Tell IT the PC name.
  • Software or vendor patches (for example metrology software updates) need a change request approved by the Quality Manager. IT installs them; users do not get admin rights.
  • After any change, the CMM programmer re-runs the verification artifact before releasing the machine.
