One thing the slides mention in passing that I cannot stress the usefulness of enough is an internal wiki. There are so many common tips, issues, ideas, etc. that can be more effectively communicated and expanded upon when they're in a centralized location for all to see. So many conversations of the form "I've never dealt with that, but I know $coworker ran into that once. Go ask him." can be reduced or eliminated if the ideas are already visibly detailed. In short, setting up an internal wiki helps improve/scale your team's productivity.
