All of my companies' internal documents contain the revision history in the form of a header. For some reason when an EO or ECO is issued, the drawing is released without a signature next to the new revision/ ECO. I have heard the argument, "Well look at the ECO, it's signed, reviewed, etc." For me, all documents should be signed and shown as reviewed including the ECO and drawing. Am I incorrect? My company is not ISO certified and our policies/procedures do not indicate any signatures, just review. See my example attached. Thanks!
