Re: Who should Sign Supplier PPAP's (production part approval process documents)?
Supplier PPAP should be reviewed in multidisciplinary approach ( with experts of all involved internal interested parties) before signing off the PSW.
This is a question of each organization based upon the responsiblity and authority of each professional figure and the organizational structure.
It could be signed off by procurement mgr, or Quality Assurance Mgr or SUpplier Quality mgmr if any, it depends.
The important is that the responsibility and autorithy are clear , defined and communicated.
Quality assurance manager is the right person to sign off the ppap document. before sigh off he will conduct all trails and checkn fit, functional and aesthatic issues. If all are acceptable then only sign off the document
