The problem with these fad methodologies is that it either works, or you are not doing it properly. The methodology can't be wrong. It is like saying that C programs never crash, because if they crash, it means you are not using C properly. It is true, but no one will pretend that, everyone knows that under real life circumstances, C programs can crash, and there are plenty of other programming languages that address this issue, at the expense of other things, like performance or simplicity. But for some reason those who push methodologies don't seem to consider that if that methodology is difficult to implement, or if it is not robust against things like conflicts of interest and office politics, or whatever, then maybe it is a problem in their methodology. It doesn't mean the methodology is bad, just that it doesn't work in every case, and that some tweaking may be necessary.
