When a manufacturer needs to change a voting system already certified by a VSTL and the EAC, they submit an Engineering Change Order (ECO).  The manufacturer submits the ECO to a VSTL.  Then, based on the VSTL's assessment of the change's impact, the VSTL determines the extent of testing required and performs that testing.  The VSTL then submits the ECO to the EAC for review.  At this point, the EAC can approve the ECO as a de minimus (minimal) change or require further testing.  If the latter - classified as a voting system modification - the manufacturer must undergo a more intensive test process through the VSTL.
