How do we proceed ? 1)

A TE DFMEA expert develops the DFMEA.

2)

His work is reviewed by a senior TE engineer before each checkpoint.

3)

This work is reviewed and discussed by the customer DFMEA team during the checkpoints.

4)

The TE DFMEA expert implement the agreed corrections and carry on the development

5)
