That's the point: they shouldn't be. A situation like that would be seen as an intolerable waste in the C-suite (with the exception of their IT support guy). However, if the status quo were for the support to be there every time, that sets up a different conversation in the executive meeting:

CEO: "Why does everything take so long to get done?"

Everyone: "We can only have 15 meetings starting at the same time, and any additional meetings must be delayed 20 minutes, because there are only 15 IT support techs."

CEO: "What?!? Is this something to do with that teleconference project? That was like a year ago!"

CIO: "That's why I've suggested to the stakeholders, most of whom are here in this meeting, that they sign off on moving to Phase 2. That way we'll have more capacity to fix the ongoing issues with desktops and printers..."

Everyone: "Absolutely not! Your techs get there ten minutes ahead of time, and usually they're still struggling to get everything working five minutes after we should have started! The system you bought is crap!"

CIO: "We've always had a great relationship with that vendor, but unfortunately their product has had a few issues..."

CEO: "I know what 'great relationship' means... I don't care if the salesmen for competing products don't have comparable expense accounts, just get something in here that works!"
