What happens when you skips steps in vendor approval

Somehow we’ve started using a new vendor for production boards that does not adhere to our PCB Vendor specifications. Some of the requirements we have in our spec are a little out of date and some items we are use to having are not in the current spec. A reevaluation of the spec was needed. We also had to change the way we do incoming inspection. Previously we received photo plots of the board layers for QC to compare to incoming boards. Generally this is no longer an industry standard practice. We’ve changes this to QC inspection only using the fabrication drawing and a silkscreen plot to compare to the boards coming in. How boards are marked to UL and Electrical Test was not clear either. This was changed so that all boards must be permanently marked as passing the electrical test. We did get the changes in the current documentation with little effort and distributed it to all the departments who are involved. Now we have to figure how a vendor was selected and used for production without going through a vendor approval process.
