> I saw at least a quarter of every working day wasted in routine status meetings, in which two or three of the ten or twelve people present spent an hour making a couple of decisions while the rest of us tried not to look too bored..
That sounds horrible. Did you mention your concerns to the people who owned those meetings, in a way that made it clear you were trying to help improve them?
I've had success several times with this in BigCo, with various satisfactory outcomes:
1. "You're right, this meeting is BS! But it has to happen for various reasons X Y Z -- since you don't care about this area you don't need to come, we'll grab you if we need you."
2. "You're right, and other people feel tuned out as well, so let's try cutting it to 10 minutes / mailing out an agenda beforehand / starting exactly on time."
3. "You're right, this is an inefficient way to gather state so we're going to just swing by each person 1-on-1."
4. "You're right, this team is too big so we're splitting in 2/3 smaller groups"
