Angle AB system is a unique supply mechanism between Angle A and Angle B. From the point of view of a single business, while Party A is fully responsible, Party B also participates in it and is jointly implemented by both parties. The main party is Angle A and the participants are Angle B, which can be replaced if necessary. This mechanism is most commonly used to set up jobs to ensure that work will not be interrupted by lack of personnel.

On the basis of implementing the post responsibility system, it is clear that each post shall be undertaken by more than two staff members. Among them, Angle A is the protagonist of his post, whose duty is to do his own job well and take the main responsibility for the work done; Angle B is the supporting role of Angle A. When Angle A is busy, it helps or cooperates with Angle A to do a good job. When traveling, vacationing or going out in Cape A, take the place of Cape A and take corresponding responsibilities for the work done.

Practical application of AB angle system.

Angle A must take the initiative to inform Angle B in writing of the work situation of the position he is responsible for, and be responsible for the skills training of Angle B. Angle B should take the initiative to familiarize himself with the work content of Angle A, learn relevant business knowledge and skills, and ensure that problems can be handled in time. In principle, Angle AB cannot go out at the same time. Under special circumstances, when angle AB is not on duty at the same time, the post work shall be arranged by the department head in a unified way, and a special person shall be appointed to perform his duties and do a good job of handover.
