It's not always easy to determine who's responsible for what in a given online project, but Google thinks it can sort out that mess. It's introducing a slew of Google Docs updates (as part of a larger G Suite upgrade) that help you delegate tasks. On the desktop, typing phrases that assign tasks will automatically suggest action items -- write "Andrea to schedule a weekly check-in" and you'll foist that duty on your colleague. Both desktop and mobile users can also manually assign items by mentioning people in comments, so it should be easier to ask for an edit or status update. You'll get a heads-up on any files with tasks assigned to you.
