AMM: CMM for Architecture?

You know, I'm surprised that I haven't encountered an effort to create a CMM-like maturity model for architecture: an Architecture Maturity Model.

Although I'm not personally a big believer in CMM, nor do I put the same weight on big-A Architecture that some do, I guess it just seems like the sort of thing that the management boards of enterprises would like to hear. "Our new billing system is AMM Level 5!"

Is there something like that lurking in TOGAF, Zachman, ITIL etc. that I haven't encountered because I've studiously avoided learning these? :)

It doesn't seem unheard of in a Google Search, but just because someone, somewhere has used the phrase doesn't mean that it's an actual movement that has any weight behind it.
