Yes, but, limiting a capable Tier Two from doing a "fix" merely because they are a Tier Two, but, otherwise capable is ludicrous, too.
Example, I a power user, have an issue with a security related app, it's not working. A Tier Two has Registry Access rights, but, has niether authority nor Install Source Access to fix the bug,
That has to go to a Tier Three... Or higher?
It's not always a pay issue... IT comes back to IT Security Paranoia needlessly segregating functionality because of a lack of trust.
If you can't trust your people get rid of them!
A few you can trust, at a higher pay level, is worth dozens you can't at any pay level!
