What’s a new CTO to do?

I wanted to get some feedback on this issue, since I know there are some CTO’s on the board…especially AMCOL.

I’m about to take a position as a CTO for a large municipal government. As a primer, I know nothing about their evironment, so I have to get up to speed pretty fast. What are some of the questions that I should be asking from day 1? What are some of the things that I should be doing in the first few months?
