I used to have a monday morning meeting with my whole department 15 or so people where they ' d give updates on their work for the week . Biggest waste of time , since 90 % of the discussion was relevant to only one or two people . The other frustrating thing that kept happening , when working alongside another department , was when I would call a meeting for some sort of system design review between myself and some more senior experts . That whole fucking department seemed to live for meetings , so before I knew it a meeting of 3 people had 6 or 7 additional people tagging along , 90 % of who had no interestknowledge in the matters to be discussed . This meant that in an effort to feel relevant they would start discussions relating to other aspects or the project , totally shifting the focus away from the actual purpose of the meeting and wasting everyone ' s time .
