Closed training in enterprises refers to a centralized training method organized by enterprises in a relatively closed environment according to their own development needs and talent training plans. Compared with external training, enterprise closed training is not only more private, but also can better ensure the quality and effect of training. Closed training in enterprises usually adopts customized training programs, which are designed and implemented according to the specific business, industry and management needs of enterprises.

The advantage of enterprise closed training is that it can provide a relatively centralized and stable training environment, and it is easier for students to concentrate on learning and skills improvement. In addition, enterprise closed training can better meet the enterprise's own development needs and management orientation, and strengthen communication and cooperation between organizations and students. Of course, closed training in enterprises also has shortcomings. For example, students may receive too much information and knowledge in a short time, making it more difficult to remember and use, and at the same time, they need to bear the pressure of concentrated study for a long time.

In order to carry out efficient closed-end training in enterprises, it is necessary to screen and match the basic information of students to ensure that their basic quality and professional background meet the training requirements. Secondly, it is necessary to formulate strict and meticulous training plans and programs, and make scientific distribution and layout for different stages and different training contents. In addition, enterprise closed training also needs to make full use of new technical means, such as social learning, online learning and cloud learning. , strengthen the interaction and interest among students, and improve the training effect and students' satisfaction.
