Do's: Focus your communication, clearly define specifications early on, set list of priorities for tasks, and aim for a minimal amount of meetings. Basic software engineering stuff, but this makes a world of difference. Leave margins for things to go wrong: you'll need them, and your programmers will love you for it.

Don't make assumptions about what is easy and difficult to build. Take advantage of the expertise of your team to assess how much time different tasks might take.
