About quality control,cant be like a fireman,immediate action required

About quality control,don't be like a fireman,must establish a preventive quality assurance system.

Voice of customer: "Immediate containment actions required

Quarantine all the slacks (from coming to US, finished assemblies and current inventory in the plant and at suppliers)

Need an answer to the following questions within next 24 hrs. (if possible,someone has to visit the supplier ASAP)
When and How many parts produced in the same batch?
Send Material Certificate for the same batch …..”

It's a painful moment when quality problem happens...

Quality system should be effectively maintained and implemented beyond the basic product quality inspection.
