Yes, the apparent successful vendor was the one I requested the price reduction. They were already the higher rated, lowest priced. I went after additional reductions. By invoking Part 15, that opens up other requirements not required by Part 8.4, i.e Debriefings, etc. etc. Part 8.4 is written with streamlined ordering procedures to increase efficiencies. If we're required to include Part 15 just because a Technical Quote needs fixed, It defeats that purpose. That's what I'm trying to get to the bottom of. How do I fix Technical Quotes while staying in Part 8.4? Further, if I've graduated to Part 15 does that mean Parts 5 and 6 now apply?
