TurbineD,
There are indeed many Performance Parameters in the F-35 Program; only a handful are "Key". None of the ones you've stated are key and certainly don't amount to hundreds either.
Of the ones that are key, rest assured they are being watched very attentively. A KPP bust invokes the Joint Requirements Oversight Council (JROC) which is a pretty messy and bad situation to be in. Nonetheless, you are right - cost is not a KPP; rather, it is an independent variable. IMHO, there have been no breaches of KPP in the last 8 or so years - minor clarifications perhaps but no breaches.
By that reasoning, it is only right that KenV has a decent answer to his question:
My I inquire as to which KPPs the F-35 "failed to meet?"
Because I'm also very interested to hear what you have to say when you get around to answering the specific question concerning the F-35's Program Of Record "KPPs" rather than what you think should be a KPP.
