6 Big Losses To achieve higher plant productivity and efficiency it is important to conduct measurements of disturbances in the manufacturing process. Disturbances can be divided into 2 categories, chronic and sporadic depending on how they occur. Chronic disturbance are usually small, hidden and complicated because they are the result of several concurrent causes. Meanwhile sporadic disturbance are more obvious since they occur quickly and as large deviations from the normal state. Chronic disturbances are more difficult to identify since they may be seen and mistaken as being the normal state. Identification of chronic disturbances is only possible through comparison of performance with the theoretical capacity of the equipment. Chronic and sporadic disturbances in the manufacturing process result in different kinds of wastages or losses. These can be defined as activities which absorb resources but create no value. The six big losses are: |
