I am in a similar position as a department of one here at Forty Mile Gas.
My motto is "my job is to make your job easier". I think you could chat with the other departments about how they use your maps/apps. Find out what they wish they had, and what frustrates them. Tag along with the field crew and look over the office staff's shoulder to see how they are using things.
Sometimes they will have suggestions. Sometimes you'll just see things that can be improved.
I blew everyone's minds when I made it possible for them to search for a meter by the account number. "you can DO that?"
Good Luck!
