Whose name should be signed by the modifier and reviewer on the completion stamp?

In the past, the unit signed by the craftsman and the responsible process engineer, but now the unit signs by the inspector and the responsible inspection engineer. Which one is correct?
Both are correct, the former goes through the process gate (department), and the latter goes through the inspection gate (department)； Usually there are only these two orifices and nothing else.
In our company, the designer signs the revision, and the review engineer signs the review. Sometimes the review engineer signs alone. I don’t know if that’s right?
It should be signed by the designer and reviewer.
On the as-built drawing, there should be a column for revisions signed by the file organizer (usually a craftsman) and a column for review signed by the responsible craftsman.
The as-built drawings should not be signed by the designers and reviewers, but should be signed and modified by the person who issued the as-built documents. Specifically, they should be implemented according to the management system of each unit.
This should have little to do with design. If it is not designed by the manufacturing unit, can you definitely implement the design sign?
If there are modifications to the design in the as-built drawing, it should be signed by the designer. If it is just the as-built dimensions, material substitution, etc., it should be signed by the archivist and the responsible engineer for inspection, but it depends on how the unit's documents stipulate it.
My opinion: 1. It should have nothing to do with the designer, because if there is a change, there will be a change notice, and the craftsman only needs to go through the procedures according to the regulations. 2. Modifications should be signed by the craftsman. reason: Before the equipment is put into production, the craftsmen will conduct a comprehensive review of the manufacturability of the equipment. If changes are required or there are problems with the drawings, the craftsmen and designers will communicate and issue a change order. The production process can only be compiled if there are no problems, so the craftsman is the modifier of the drawings. 3. The review shall be signed by the chief quality inspector. reason: The chief quality inspector is the final inspector of the quality of all factory products. Among them, materials, flaw detection, comprehensive quality, etc., are they related to design and process? * * Whether the standard requirements are met or not is within the scope of their work. Whether the changes have been modified and substituted in a timely manner, or whether the manufactured products are consistent with the as-built drawings, must be signed and confirmed by the chief inspector. (Strictly speaking, without the signature of the quality assurance engineer, the product cannot be approved by the quality assurance engineer and cannot leave the factory).
We are the designers signing the revisions, and the reviewers signing the reviews.
As-built drawings are drawings drawn based on the actual completion status of the equipment after the equipment has been manufactured. They can also be modified from construction drawings. If it is drawn separately, it must be signed by the person who drew it. Because there is a drawing process, it is best to have the person in charge of the process review and sign. If it is modified from construction drawings, I think it is best for the inspector and the responsible engineer to sign on the construction drawings directly.
In our unit, the inspector signs the revision, and the responsible inspection engineer signs the review.
We are the designers signing the revisions and the design responsible engineer signing the reviewers.
