It is valuable if you do it right, but it's difficult.

I've been promoting a specific aspect of performance quality recently, but it's mostly lead to other teams creating tests to monitor it that don't really make sense (along the lines of "if you use the computer it'll make the CPU % go up"), asking me to look at it, and then when I say it's probably fine I get a response along the lines of "it must be important because we already told all the executives about it."
