Oh yeah, I'm not saying that people are actually following the spirit of NIMS, and that a lot of unqualified people are put in charge, but I wouldn't call THAT the fault of NIMS, I'd call that the Peter Principal at work
No, it's not at all that.
So, here's my experience: years of active duty firefighting, but not as many as most of the other guys at the firehouse (typical tenure of the core group is 20+ years).
But when the river came up, and we activated NIMS in a basic sense, I was pushed all the way to IC because, unlike the guys with more operational experience, I can use a computer, make spreadsheets, slide shows and find information online. I can do the NFIRS reports - basically, my competency was 25% operational and 75% administrative. And that's what NIMS is. It's an administration tool built by administrators for administrators and while it - supposedly - makes operational processes better, I see it as a means - first - of tracking the money and secondarily a means of making on the ground operations more efficient.
NIMS is, at best, politically and socially naive, and at worst, it represents a kind of thinking about government services that makes me cringe.
