Overblown salary! I Wish!
Remember the last guy running the yield control dept? Hewas similarly qualified and his models and ideas caused us more trouble than ever.
You need good internal data to run these systems, once you have that they almost run themselves.
GF doesn't have any, never has.
What they do have is so far scattered around the four corners of HDQ it is (almost) impossible to make anything meaningful of it. Little is shared, little is accurate. Hence all the bad decisions.
If you are that close to GF you should know that too, but of course your mates are the ones who can see the wood for the trees anyway, so how could you!
I don't 'hate' anyone as you put, just largely disappointed that so many fools can survive so long. But then that is what happens when your boss knows less than you and you are an 'ace brown-noser' like so many on that particular floor.
