I have already written about the difference between the COT and DOT that there is really a difference between this and that there is a difference in the provided knowledge and how it is provided. We spoke a lot about receiving data and analyzing data, exchanged some thoughts about our area and division strategy and overall helped each other out with bigger topics like hybrid meetings and so on.
Overall, I will mis this DOTs the most, such a warm and welcoming atmosphere and so well prepared.
