I'm lazy. We are all lazy, aren't we? So I want to make it as easy as possible for the agents.
So it is easier to say, open ticket system and look if something to do.
If I say, open ticket system, first check open queue then check 'my tickets', this is one step more. One step, I know. But I have worked over 10 years as instructor and one mandra is: If you can do something in one step. Make one step, not two or more. I know, with time, agent forget to check 'my tickets'.
