I'm in the process of restructuring our document numbering system. Right now we have QCWF-126.96.36.199-01 (Name of Document). I think it's silly I want to change procedures to P001 and so on, Forms to F001 and so on, Work Instructions to WI001 and so on. We have a lot of other documents that don't really fall into any of those categories. More of reference documents. I don't want to call them R001 because I think people would assume they are records. Any suggestions?
