What is the biggest advantage of people with similar levels getting together? It is to reduce communication costs. Do you have this feeling? Because meaningful communication can only occur when knowledge and information are synchronized. When two people have relevant knowledge, many simple concepts can be skipped directly. Why is it that sometimes a glance, a few words can make things clear? Why is it that in some companies, it is completely difficult to implement between superiors and subordinates or colleagues, difficult to implement on the ground. It's because the boundaries of knowledge are different. If our knowledge boundaries and contents are the same, many basic things don't need to be explained again, and the communication cost will be particularly low.
