Bill Easum has a nice post on the Top Six Tactical Mistakes Churches Make, and a second with Two More. via
I like his point about the announcements (they should not be the first thing you do, because they're like commercials, and nobody likes commercials, so why would we start out with all of them at once?). We usually do announcements first - though recently I had been starting with a song and then doing announcements. I am thinking about moving them back to when we take up our offering (which is when Willowcreek has done them when I've been there). And they need to be wayyyy minimized. I have put them on the screen before the start of the service before, but I don't think people read them, and it takes me too much time.
The other thing I liked was the deal about children not being the future. Not that they're NOT the future - they are - but as I've always said, they are the present too!
