A Quality Management System (QMS) should monitor and measure a CM’s manufacturing activity and verify that product requirements are being consistently met. An SPC (Statistical Process Control) team should also be in place to monitor inspection and test results from each key process area and identify areas requiring improvement. Quality processes begin well before production, starting with suppliers and compliance with industry standards, and continuing with manufacturability, testing, and services, along with creation and strict management of all necessary documentation, including change control.
