Q: How to call the meeting? "stand up?", "huddle?", other?
A: Call it a Stand-Up - and remind people about this, especially the long-winded ones. People who sit are in no hurry to end meetings - hence the invention of the more uncomfortable stand-up.
Q: I have worked in some places where before the scrum meeting the scrum master touches on the latest news (political, technology, etc). Should I do the same?
A: That depends on the company culture - and since you're spread over (at least) 2 time-zones I would advise against anything political; you don't want to step on anybody's toes - and not even be able to see that you did it.
If you're entertaining, you could mention something about the latest technological news; but remember, you may be boring a lot of people, and you cannot see them to gauge their interest.
Q: Should I be the first or last to talk in the status presentation?
A: Both! You should start by officially starting the meeting with a standard line. E.g. G' Day Team! You're all standing, right? Let's start today an update from ______.
You then call on each team in turn and end off with a summary, some invigorating statement and a reminder to show up at the next meeting tomorrow/Monday/whenever.
Q: What other points should I cover?
A: People like it short and like information/updates: We're 3 weeks from release - expect a press release bla bla bla. Matt will be on vacation from ___ for 2 weeks; Jane will be covering for him. Congratulations to ____ on _____.
Q: Are there any books on this subject?
A: I'm sure there are! But I haven't read any, yet. (I am toying with the idea of writing one.)
One last piece of free advice: Get a tripod and have somebody video the meetings - and make the MP4s available for those who have trouble keeping up, or miss it or come late/leave early. (And please don't email MP4s - just send a link.)
