1. Too much efficiency. You need some slack.
2. Inflexible systems. There's normally room for improvement.
3. An undying belief in technology (e.g. e-mail) over people stuff (e.g conversations).
4. Board-room tables. Between people.
5. Yellow stickies. Everywhere.
6. 1h chunks of time in the schedule. Choose 45 minutes and have a gap before the next meeting.
7. TV. Oh, yes.
