Performing a motion study
Every job can be broken down into its’ fundamental work elements. The Gilbreth family found that there are seventeen of these motions. The time to complete each motion does not change. This is the important part. Jobs can be studied visually or through the assistance of a camera for micro-motion studies.
Whether the study is visual or micro the IE will be applying the same rules of motion economy to the person, environment and tools. The rules that are applied to the person, intend to help the person move in a more balanced and synchronized manner. For example, both hands should begin and end moving at around the same time. Foot pedal devices should only be used when the operator can sit down.
The environment for the workers also needs to be set up to promote efficiency of work. Tools should be placed in fixed locations to eliminate the search and selection therbligs. Work surfaces and chairs should be adjusted to the correct working heights to eliminate stress. Whenever possible, gravity feeders should be used to deliver parts to the correct location. The worker's tools should be designed to eliminate multiple cuts. Adjustment handles should be designed to maximize the operator’s mechanical advantage.
The process above is a continuous process. To stay competitive companies must continue to increase the production capacity of their facilities while reducing their cost. The IE will be expected to come up with additional improvements each year.
