List out all your common changes, and produce a checklist template for implementation. This checklist should NOT be page after page of screenshots that nobody but the greenest admin will ever read. They should be concise, and contain just enough information to have all the implementation data, and jog the memory of the admin as to precisely which steps need to be done.
On the template, you should record all the data you can possibly need to implement the change. If you could not fill out the checklist, and then hand it to another admin for implementation, the checklist isn't good enough.
So, that covers the change request part of the checklist.
In the actual implementation part, record ALL the steps where there's a decision point. (As in, you don't need steps for "Remote in to admin console, Login to Switch Config App, Login to Switch, Enter Config mode, enter VLAN subsystem, etc.) "Add VLANs to switch, using information listed above" is fine. Make sure the checklist includes updating whatever documentation you have.
Each line on the checklist should contain the date/time the step was completed. (If the admin just has to put an "X" there, guaranteed they'll ignore the checklist and just put in the "X"'s at the end.
Make the filled-out checklist itself part of the change record. Your change records should be complete enough that you should, in theory, be able to take the pre-change-system config, execute the tickets one after another, and end up with the same final config.
Lastly, do NOT require mgmt. approval for routine changes. Your checklist should already cover giving the appropriate people warning of the change. If you require mgmt. approval (or a change control board) for the most trivial changes, it quickly becomes rubber-stamping, which is even worse than wasting everybody's time. Save the change review process for changes not covered by the checklist.
