Assigning works with similar standard time as close as possible to achieve a balance production line. However, the productivities of operators should be different due to pressure from diverse production conditions. Three different production conditions were investigated in the study to understand the relation between production amount, yield and WIP levels. Three production conditions are no pressure, posterior faster operator, and posterior slower operator. No pressure condition is the operator under investigation works with his own speed. The other two conditions are all assign a faster operator prior the operator under investigation and give him pressure and then assign a faster operator or slow operator after the operator under investigation to simulate the regular conditions we have seen in a real production scene. Twenty college students were recruited in the study. All students were participated three production conditions. (no pressure, faster OP-OP under investigation- faster OP, and faster OP-OP under investigation- slower OP) The results show that the least production amount was found at no pressure condition and there is no significant difference between posterior faster operator, and posterior slower operator. There is also no significant difference among three conditions in production yield. Furthermore, there is no significant difference in WIP level whether the speeds of posterior operators are fast or not. The possible reason for the study results is the reward system. We paid according to their production amount. Hence, the operator under investigation ignores the speed of the operators after him to get more money. Finally, the study suggests the following researchers can aim at the relation between production performance and surrounding pressure under different rewarding systems.
