The principle of opening and closing means opening to expansion and closing to modification. When the program needs to be expanded, the original code cannot be modified, but the original code should be expanded to achieve a hot plug effect. Therefore, a summary of one sentence is: in order to make the program scalable, easy to maintain and upgrade. To achieve this effect, we need to use interfaces and abstract classes, etc. We will mention this point in the later specific design.

Researchers used standard psychological methods to study the changes in climbers' brains when they analyzed various handles. They first noticed that experienced climbers and novices can identify each handle according to the type of grip they need. For example, in their psychological representation of various handles, all those handles that need to be grasped by wrinkle methods form a group and are distinguished from handles that need to be grasped by other methods. This grouping method is unconscious, just like when you see poodles and Great Dans, you immediately know that they are all members of the canine family, instead of saying to yourself, "Both are dogs."

1. Normal life cycle:
JIT theory holds that the most precious wealth of an enterprise is not the machine building or the product, but the employees in the production line. Employees are the source of wisdom for enterprise development. Only when front-line employees meet the requirements in their operations can the system truly realize its functions. Only when each employee exerts his creative ability can the whole system acquire real dynamic adaptability and self-improvement ability. If employees do not understand JIT production, do not actively participate in production activities, do not play their own independent spirit, and do not participate in enterprise improvement activities, the problems in production will not be exposed and solved. The secret of the success of JIT production mode lies in "full participation". One of its important characteristics is endless improvement. To this end, enterprises have invested a lot of energy in various aspects of training to improve the quality of employees. Teamwork, multi-ability in one post and multi-machine in one person have all become necessary skills for frontline employees. JIT production mode realizes the overall flexibility of the system through the operation of the organization and the high ability of employees.
