Try thirty days, when the CFO's password expires, and IT isn't there to reset it for him, or remind him of the web site we set up so he could do it himself...
(And yes, I have seen 3rd level and higher managers refuse to click twice and enter a new password, more than once, even when the people with the authority to circumvent the established process were out of the building.)

I'm not terribly concerned that CIOs are not considered key players in determining business strategy, whatever that may mean. CIOs aren't supposed to determine strategy for the overall business - they're supposed to support the strategy set by the CEO, and communicate real-world expectations to the executives about what IT can and cannot do to help. The CIOs who do set business strategy are the scarey ones - because they often don't understand IT.
