I imagined that this was going to be a S03E01 of Red Dwarf type scenario where you get handed some notes and a few action items and then apologize for leaving early. But no, it's office hours.
""In a reverse meeting scenario, by contrast, I might take only 10 minutes from each colleague, taking up 50 minutes total of my time, and 50 minutes total of their time, for an overall demand of 100 minutes of attention, which is 3.6 times less cost," Newport writes. And voilà, he's just given your team back more than four hours of productive time a week."
Assuming that people manage to show up in perfect slots with no conflict and do so in a way that has perfect utilization for the victim and that there is no value in having someone point out that one of those 10 minute slots was full of incorrect information sending you down a two week rabbit hole that could have easily been avoided by having the right people spend some time together.
In a perfect world my ideal meeting situation is the meeting defragmenter. This involves software and cooperation unfortunately so the next best solution is out of office hours. I need focused time to get stuff done and blocking large chunks of meeting repelling time is really the only thing that works.
