How often would the CEO even be involved? Very small companies excepted, I would think this would be something entirely delegated to the CTO, manager, or whoever is in charge of technology in the organization.

Lots of CEOs want to rubber stamp things in SMid companies even if they're actually not doing the cost/benefit themselves. This page probably comes in handy for the CTO/MGR who has to get that rubber stamp from the CEO. (that's my guess at least)
