It is a ratio of standard work time to operation work time, which is a representative
index for the performance of the manufacturing field. Moreover, it is a result of manager’s
efficiency and operator’s efficiency.
- Expressed in multiplying actual work rate (manager’s efficiency) by actual work time efficiency
(operator’s efficiency).
- If operation work time efficiency is low, improvement points can be calculated through examining
actual work rate and actual work time efficiency that are the main elements of this index.
