At mid day on Day 1, I felt that we had spent too much time on fundamentals of Scrum. For an A-CSM course, I expected to jump straight into more advanced topics. I enjoyed Day 2 more for that reason. I also realized that some so-called 'basic' topics are more nuanced than I thought.
Day one felt like there wasn't a lot of structure. With people from so many varied backgrounds, the conversation was sometimes derailed with very specific problems of one person. There wasn't much conversational equality, with 3-4 people dominating with their 'answers'.
