mutt:
OK enlighten us, what product are you trying to sell?
I presume you are speaking to me.
I don't sell anything other than my flight operations and instrument procedures expertise. I don't design instrument procedures, either; way too much liability. Only Boeing and G.E. have deep enough pockets to do that.
I also don't deal in snake oil, unlike some performance engineering departments I have dealt with.
(present company excepted, of course.)
I also find it incredulous that performance engineering is mostly still in the 1970s as to OEI flight path navigation. VOR systems, as one example, cannot deliver the accuracy presumed by some (many? most?) performance engineering departments. RNAV, and especially RNP, can deliver the goods, so to speak. No marketing concepts there.
