The crucial point being that "when done well" is something that you usually
can't evaluate until it's too late.  And there's maturity level for more than
just products and implementations.

It's clearly possible to find telco engineers with 5/10/15 years experience in
running PSTN (might even find somebody with 40-50 years? :).  It's possible to
find network engineers with lots of BGP experience. Where do you find a senior
engineer with 5+ years experience in enterprise-scale VoIP deployment?
