It is interesting at this point to think about everything that has contributed to this conclusion. First and foremost, of course, I had fun. All my hobbies were waiting for me practically at the front door.
Before I started, however, I thought about how well I could create a balance between accessibility and efficiency and, on the other hand, games, fun, and joy. Of course, it has been explicitly communicated in the team so far that it essentially doesn't matter when and how much everyone works. The main thing is that the tasks are completed and if not, that that information is communicated appropriately. Nevertheless, it's an interesting experiment to see what happens when you completely ignore common notions of core working hours.
Even if the timing was rather unfavorable, I think that the first week with the release was very important for proving that we could fully rely on each other. I knew it was important, so I was there. From the second week onwards, I tended to arrange my working hours according to the weather. It's quite unconventional to first communicate when you'll be available the evening before or sometimes even on the same day. On sunny days I only worked on important and/or urgent tasks. Of course, this led to the fact that I worked less time overall than I would usually do in the office. Time and again, this led me to ask myself very consciously: is everything going as it should? Yes? Then I can take time off.
An experiment wouldn't be an experiment if you didn't also have doubts. It was clear to me that I also had to do small things that I would normally have simply worked on with two hours more time. In this respect, one always weighs up in the background whether what one is doing is sufficient, because one could achieve considerably more if one worked eight hours instead of four. It's not just me who notices this, but everyone. The communication within the team was extremely pleasant: when in doubt, just ask if there's anything left to do.
