DPI vs PM: During Production Inspection or Production Monitoring

What Quality Control Service to Chose ?

As importers it is very important to keep your eyes on your production in China or Asia. Why ? The answer is simple, spotting problems or defects before is much more cheaper than later (and avoiding problems  even more). I can do no other than advise you to systematically inspect your production from China.

For those who need to watch closely after their production, there are two solutions.

Each solution has its advantages. Let’s develop.

DPI – During Production Inspection in China and Asia

The principle of During Production Inspection in China or Asia, is to send an inspector (engineer or technician), in the factory to check your production, and identify potential problems. In general, each inspection last one day, and you have to repeat the process for every strategic step of your production.

What are strategic step of production in China and Asia ? This scheme will help you identify main risks in your production process:

China Quality Inspection Time Line

This inspections aims to check three major points:

  • Raw Material
  • Process
  • Product quality

They are then assessed against importers specification and requirement. The production situation, can be controlled and confronted your manufacturer commitment. It aim to check best practices are respected.

If some issue are detected, you can resort to the following process:

  • The inspector edit a Corrective Action Request (CAR)
  • The quality manager incite your manufacturer to build a Corrective Action Plan (CAP)
  • The inspector control the effective application of the Corrective Action Plan

PM – Production Monitoring in China and Asia

Unlike During Production Inspection, witch aim to send an inspector on site several time to control the quality of your production, Production monitoring is about allocating an inspector to the factory to supervise the whole production. I recommend Production Monitoring service to those who are manufacturing heavy machinery or running complex project in China or Asia.

The inspector will keep an eye on your production during the whole inspection period in addition to following the same quality control process as a standard inspection.

As the inspector stay in the factory and control the whole production process and quality, instead of provide photos, he/she gives a film about the situation. This allow buyers to have a complete point of view of what happens in the factory.

To organize their report, inspector usually resort to a Gantt Chart. This diagram helps showing each step of the production, preventive dates and actual dates. Here is an example:

One of the advantage of Production monitoring service stand in corrective action plan supervision and report in real time. As it buyer are aware of the well being and effective application of corrective plan in the factory.

I would say the other advantage remain the possibility for inspector to learn more about your supply chain, and having access to those information is valuable for buyers. But, this could happens only when relationships between manufacturer and inspector stays relatively courteous.
