Yes. I worked in an agile shop some years ago. We did daily stand-ups at 10:00. So, you arrive in the morning, and can't really get deeply into anything because stand-up is coming up. Then stand-up ends and you maybe have a sidebar conversation at the coffee machine, you get back to your desk and now lunch is coming up, so you look for some stuff you can do quickly, maybe read your email, check HN, whatever. After lunch you might get a few unbroken hours to really make progress on something, but half the time it's interrupted by code reviews, planning poker, or some other agile ceremony and the same sort of effect occurs.
