Field operation analysis usually includes three types: operational analysis, work and simplification, and method engineering. Job analysis usually includes three types: operation analysis, work and simplification, and method engineering. The research purpose is to reduce unnecessary work steps, or to complete necessary operations in the fastest, safest, and most comfortable way. Action analysis can be divided into five principles and twenty-seven items: Article 1 Principles of Human Movement (1) Use of hands for productive work ； (2) Both hands start and complete various symmetrical tasks at the same time ； (3) Make the movement of hands and arms make continuous curves ； (4) Work should have a rhythm to make the work automatic and smooth ； (5) Within the operating range, try to keep the moving distance as short as possible and use the lowest category of movements. Article 2 Principles on the Workplace (1) Movement paths of hands and arms should be within the normal working area ； (2) For work that requires attention with eyes, normal vision should be ensured ； (3) Tools and materials should be placed in fixed locations ； (4) The height of the workplace should be designed to allow standing or sitting use ； (5) The working area should be based on the principle of minimal movement ； (6) A good working environment can lead to good work performance. Article 3 Principles on Tools and Equipment (1) Tools and equipment should be placed within easy reach or grasp ； (2) Use foot pedals and fixed tools to replace hand movements so that the hands can perform more useful tasks ； (3) Use automatic pop-up facilities to remove completed products ； (4) Arrange the machine controls properly for easy operation ； (5) Use of special tools and compound tools (multi-purpose tools) ； (6) Consider how to use the machine to facilitate operation. Article 4 Principles on Material Handling (1) To facilitate capture, there should be good design ； (2) Arrange gravity conveying hoppers, separators, stacks and conveyor belts to deliver materials to the place of use ； (3) Preset and classify materials and parts required for the next operation ； (4) Use floor-to-ceiling conveying method to move products away ； (5) Use handling machinery when lifting all heavy items. Article 5 Principles of Time Saving (1) Improve the problem of hesitation or temporary cessation of manual and mechanical actions ； (2) Generally, action forms that require fewer steps or elements take the shortest time. ； (3) When the machine is working, the work should be in progress ； While the work is in progress, the machine should be working. Article 6 Filling in method (1) Operation steps must be recorded in detail according to the work process ； (2) The operation methods should be recorded in detail in the operation steps and procedures. The operation methods should be described in plain words as much as possible so that employees can easily understand them. ； (3) When the machine is working, the work should be in progress, and when the work is in progress, the machine should be working ； (4) Two or more parts should be processed at the same time ； (5) If the description of the operation method is incomplete, diagrams should be used to assist the explanation. Those who can draw should try to use diagrams to make it easy for the operator to understand. ；
