Good luck to you in your pre-assessment......take the opportunity to "pick " your auditors brains a little....as far as the 4.20 thing goes, I called out analysis of various reliability measures, MTBF, MTTS, LCC, etc.....and then showed that we were doing some analysis of these measures to drive improvement. I did some analysis of LCC; gathered estimated production/labor/material costs, and did some comparisons with actual times, etc. I based our MTBF, and MTTR numbers on individual components testing, and then ran those failure rates into a system reliability formula (series vs. parallel systems) It worked out fairly well, and I was even surprised by some of the numbers I got back. We use this information to help drive process improvement........
I get the feeling that this TE thing is so new, that there will be some fumbling and groping by all parties concerned......if the numbers I hear about the sheer quantity of TE suppliers as opposed to production part suppliers to Detroit, this TE thing should be huge. I guess it will come down to customer mandate..........we shall see.
Keep us posted on your experiences.
