Enterprise Architect: 11 mandatory hours this week, and a number of regular meetings have been canceled. Optional meetings amount to around 7 hours this week; pretty light.

At my busiest, it is closer to 30 hours a week, and my longest regular meeting is a quarterly planning offsite that's ~3x 8 hour days.

EDIT: I can't say that I resent any of these, since they're simply a part of the job. My role has a component that I have come to call 'state synchronization'. I act as a bridge between multiple groups by syncing up technical knowledge, status, and blockers between the various engineering groups (and other technical leadership) who I work with.

Standups work great for small groups, but they don't scale well beyond 10-15 people.
