If a problem came up I was expected to text or call a manager. As you can imagine, they did not often reply or pick up.
Many problems require rather immediate solutions.
These are not your problems. If management has enacted a procedure that doesn't work, don't change it or you will be blamed for any failure.
Send a few emails to document your opinion that there are problems. Otherwise, do exactly what was recommended. You want the policy to fail. Don't try to improve it without management support.
