See my blog on this topic, here excerpted:
"subcontractors in charge of processes which are essential for ensuring compliance with legal requirements ('critical subcontractor') or a supplier of crucial components or of the entire devices (both: 'crucial supplier')".
If we think of subcontractors as responsible for processes and suppliers as responsible for components, the GHTF document is then useful in this regard (see page 11 of 21, GHTF/SG3/N17R9:2008). Manufacturers should consider identifying suppliers according to these terms for managing not only its supplier quality program, but also to provide meaningful direction to its registrar when the unannounced auditor knocks at the door. Suppliers that provide parts and components made to your specifications (e.g., mechanical, electrical, software) belong on your list of "crucial suppliers". Suppliers that provide services related to processes (e.g., sterilization, design, environmental monitoring, manufacturing) belong on your list of "critical subcontractors".

As a member of a small startup, we would like to know how the device industry defines critical suppliers. I work with many engineers and we do not seem to have to good definition of critical suppliers. To them, everything is critical because the supplied parts all seem to affect patient safety. I would like some opinion on this.
Thanks.
