Even for my initial two years of experience, we (developer) were not even having permissions to view execution plans or ever briefed about indexing & other performance concepts.

So please help me by answering below 8 questions in order to find the solution that could bride this gap and help the developers to earn the privilege. I will publish the results of this survey, along with conclusion once we have considerable vote counts.
