Baya is Ali's training meeting. Baya is a system composed of people, so what this system needs to do in essence is to organize people, which is the core element. Man is a complex creature, whose inner movement and behavior are unpredictable, which is also the reason why it is very difficult to organize people. In just five days and four nights, we can effectively organize a group of strangers to form combat effectiveness and finally achieve the system goal. Therefore, the analysis of Baya should focus on how Baya organizes people. As a programmer, I used to pay more attention to how to effectively organize technical components to achieve business goals, but now thinking about the system from the perspective of people will bring me more inspiration.
