Dear Technetters:

Here's a situation where your opinions would be helpful:

Assume
your company  have shipped a PWB to a customer and the customer
determines a functional failure and via XRAY determines that there was
problem via a solder short. As the builder you review the XRAY image
and you confirm that it is indeed a short. The customer asks you for an
8D analysis. You politely request that the board be returned so that
you can ask the 5 "Whys" or generate an "Ishikawa diagram" or a get to a root cause.

Upon asking this question the customer indicates that the board is no longer available. Do you:

A. Tel the customer that without the actual board (1 out of a lot size of 25) the root cause analysis is not possible and you cannot perfom an 8D
B. Ask for the balance of the lot back to see and begin the root analysis and trust that you can actually get to a root cause
C. Guess at a root cause 
D. Do not answer your phone

Regards
