We have a Quality framework and each elements falls under its key standard. For example Personal Hygiene is under People Standard. Therefore if we have handling bread procedure, then the document number would look like this:
GF: company name.
PPS: abbreviation for People Standard
Baking: to specify which business division this document relates to. We have several divisions (dairy, baking, grocery). For general procedure that applies to all, e.g., hand washing then we would use 'Group'.
QA: Quality Assurance
Procedure: document type. Other options: Policy, Standard, Template, Training, Reference.
001: sequential number.
Hope this is helpful. It is important to consider the future and outside of QA related documents when generating the document number. With our format, any other department could easily adopt our document number, by simply changing QA to R&D.
Good luck :)
