Below is a list of processes and procedures EMS providers should have in place, and filed in their document control department, to help manage quality integrity of provider service offerings for OEM product programs.

This list is not comprehensive but can be used as a guideline.

The list is arranged by upper-level quality subject or function, followed by subsequent or corresponding related processes or procedures for that subject or function.

For EMS providers, this list can be used to determine if any quality-related processes or procedures are missing to help build OEM confidence in provider capabilities.

For OEMs, this list can help you gain a greater depth of understanding during your provider evaluation process in terms of an EMS provider’s scope of understanding quality, and relevant processes and procedures the provider has in place (or needing to be implemented), to meet minimum industry standards.

This list was compiled over several years working with both OEM and EMS companies. QRA stands for quantitative or qualified risk assessment. (See, also: Driving a quality focus in manufacturing teams)
