Lots of sprint ceremonies / processes / meetings mean time to focus on actual project work is hindered. Focus time is needed i.e. it take 15 mintues to prep for a meeting, 15 minutes to refocus on task afterward. A 30 minute meeting turns into an hour and having these scattered throughout the day really does hinder efficiency. During my first few weeks I caught glimpse of someones google calendar and saw it bursting with multi-coloured meeting events (sometimes overlapping 3-fold) to the extent it resembled a picasso painting.
