We have come together with a solution for our product drawings.... This will help prioritize the work and prevent resources being spent on a drawing that is not needed until our permanent solution is in place.
Sounds like a good and practical solution. Well done. Naturally you (the company I mean) will need to keep working through and gradually get them all fixed, which will presumably get a lot easier when you have the new manager/new resource etc.
But in the meantime, you're managing it which is the point. And making sure there's only one true copy and that it's available to the person/people who needs it and that unauthorised copies are not.
Also, another question I have is in regards to handwritten changes. He have some product drawings that due to timeline restraints the engineer didn't have time to create a new drawing so he noted the changes, initialed them and then scanned it onto the server as a pdf. This has been a big discussion in my group whether or not this would be acceptable.
Sounds like another practical solution to the problem. Just make sure that it doesn't conflict with your written procedure - ie, make sure that allows for it.
As an auditor, I'd also expect to see evidence that this whole issue of control of engineering drawings was known to management and being actively monitored (eg, agenda item, meeting action/minutes etc).
