My manager, let's call him "Bob", is not very keen on deadlines. He rarely, if ever, sets actual deadlines for when things need to be accomplished. To compensate for this, I create my own timelines with various milestones for my projects to make sure I'm on schedule.
The issue I'm running in to is that there are things I can't do on my own - they require Bob (since he is also our acting DBA) to do them. I will send an email basically saying "for [some project], I need [such and such] done. If possible, I'd like to have this done by [date]. Thanks." These emails are mostly ignored.
Is it appropriate for me to ask my superior to do what I need to meet these deadlines that I have created? Can I follow-up with Bob until it's actually done, or is this "role reversal"?
