(A) the overall principle analysis of the project practice of management trainees. From the perspective of enterprise management trainee project, enterprise management trainee project is equivalent to a whole, and the factors that play a role in this project, such as the level of trainers, the quality of trainers, training input, etc., constitute the various elements of the system. A perfect management trainee plan consists of nine elements: enterprise status, management attention, investment, training plan, trainer skills, training environment, trainee quality and training feedback. As far as the whole project is concerned, it must ensure all the elements to play its greatest function. Therefore, in the implementation of the management trainee project, each element needs to play the greatest role in the whole. For example, enterprises have excellent trainers, but the project funds are insufficient to start, so it is difficult to make the project go smoothly. For example, if an enterprise has sufficient funds to train teachers, and if the quality of the recruited students is low, it will be difficult to achieve the training objectives of the enterprise. Only when each of the nine elements reaches the best state can the whole play its greatest role. Just like the relationship between the above nine elements: the current situation of the enterprise determines whether the management attaches importance to the project, that is, the management attaches importance to it. The higher the management attaches importance to it, the more funds will be invested, and vice versa. The amount of investment directly affects the implementation of the training plan. Training plan, trainer's skills, trainee's quality, training environment and trainee's salary are the direct reasons that affect the implementation effect of management trainees, and are the result of the joint action of internal and external factors. Training feedback is an important factor to test the training effect. Without training feedback, it is difficult to effectively control the whole training program, which can be described as failure. It can be seen that the nine elements are interrelated, influential and indispensable.

(2) Analysis on the feedback principle of management trainees' project practice. People's cognitive process, whether for a specific understanding or for the whole cognitive process, can also be understood from the perspective of information feedback. Human cognition is a dynamic reflection of the outside world, that is, processing information on the basis of receiving external signals, and feeding the processed information back to the input end as input information for further processing, and then feeding it back again until a specific cognition is reached. To achieve a specific understanding, that is, to achieve a stable state of understanding. Therefore, for the project of enterprise management trainees, the corresponding feedback mechanism should be established before, during and after training: 1. Before training: listen to the opinions of the company's senior management, obtain information through questionnaires, interviews, etc., so as to make a good management training plan. The design of the questionnaire should first consider many factors, such as corporate goals, corporate culture, the comprehensive quality of executives and management style. Thirdly, the collected feedback questionnaires are screened, and some experts are invited to help analyze them from multiple angles, so that the training plan can better match the corporate goals and corporate culture and make it more systematic and scientific. 2. Training: Through the timely feedback of the trainees, adjust the corresponding training plan and establish an LTP mode combining learning, thinking and practice. L stands for "learning", T stands for "thinking", P stands for "practice", and LTP is connected into a triangle. Management trainees can stabilize their training knowledge through this triangular structure and feedback their learning and practice through thinking. 3. After the training, feedback should be given regularly and timely according to the students' practical situation, because after the training, each student will be assigned to a different post, so everyone will face new problems. This is because negative feedback is necessary for the control of a system to achieve a certain goal stably. But besides negative feedback, positive feedback makes the system deviate from a certain goal more and more. Generally speaking, positive feedback should be avoided, but it must not be considered "bad". Positive feedback leads to system instability and changes in system structure. If our goal is to destroy the old structure of the system in order to establish a new structure, then we need to achieve this goal through positive feedback. If you don't always get feedback information in time, the system can't achieve effective control.

(3) Analysis of the orderly principle of project implementation for management trainees. No non-open system can spontaneously change from disorder to order, that is, it is impossible to change from a lower-level structure to a higher-level structure. First of all, the principle of order tells us that the system must be completely open, so that the system and the environment can continuously exchange material, energy and information, which is an important means of system development, so the openness of the system has an important impact on its evolution. Therefore, it is necessary to implement the management trainee program in an open enterprise environment. Only in an open enterprise atmosphere can all elements fully exchange information with the outside world. Such as trainer's skills, training plan, training methods and training items (including team spirit building, employee loyalty and professionalism training, manager temperament training, professional skills training, etc.). ), these important elements can only be distinguished from external energy and information and selectively absorbed, so as to change their own defects and deficiencies and make the management trainee project better adapt to this enterprise. At present, some multinational companies have adopted overseas companies' training plans too much in their local management trainee plans, ignoring the link of localization, which is a manifestation of insufficient openness. In fact, most multinational companies do business in China, and most companies have employees in China, so they can't completely westernize companies. Therefore, when multinational companies implement the management trainer program in China, they should learn more from the management trainee programs and projects of some large enterprises in China. Secondly, the principle of order tells us that order is achieved through fluctuation. Fluctuation is that a variable or a behavior in the system deviates from the equilibrium value, which makes the system leave the original state or trajectory. Whether the fluctuation can be amplified depends on whether the system is far from equilibrium and whether there is a suitable nonlinear interaction mechanism in the system. Different waves represent different related movements, which compete with each other and with the original structure. Once the conditions are met, the situation will change fundamentally, the correlation scale between fluctuations will increase rapidly, and the connection between different fluctuations will be strengthened, eventually forming a huge macro-scale fluctuation. This fluctuation actually represents a new organizational model. Once this organizational model is stabilized by the system mechanism, it forms a certain dissipative structure. Therefore, we can know that for a self-organizing system in a certain stable state, if there is no fluctuation, it is impossible for the system to realize the existence of other possible stable States, that is, to achieve order through fluctuation, that is, to achieve synergy through competition in essence, and to start a new interaction between competition and synergy on a new basis. Therefore, in the enterprise management trainee project, different periods need different degrees of fluctuation to break the original balance. For example, in the late 1990s, in the labor market where talents were scarce, the training industry was still relatively immature. Therefore, most of the management trainee plans formulated by enterprises are relatively simple, with poor training environment and low level of trainers. In today's fierce competition in the talent market, the original management training system has been in an extremely unstable state, such as a single training plan, lack of funds, and increased job opportunities in the human market. The original training programs and plans can no longer adapt to today's labor market, which will cause instability and qualitative change of the whole management training system. Because of the amplification of this fluctuation, the system is far from the equilibrium state, so it is easier to realize huge fluctuation, which will make the system transition from unstable state to new stable and orderly state. Today, according to the principle of order, the implementation of the management trainee plan should focus on how to improve the satisfaction, loyalty and professionalism of employees, which will help enterprises retain talents and promote the orderly development of enterprises. As Harken, the founder of Synergetics, said, "The interaction of fluctuation and elimination led to the evolution of the system." However, Www.bfblw.com, we should also realize that there is another possibility to induce system evolution through fluctuation-fluctuation will lead to system collapse. If the fluctuation can't be absorbed by the system, it will become redundant force, which will make the system morbid and lead to system collapse. Therefore, it is suggested that the project researchers of management trainees master all kinds of effective information about the operation and development of the project, and can diagnose and find all kinds of problems in the operation of the training project in time, so as to make correct decisions.
