Summary Introduction
Case summary:
Person K is the vice-president of operations at Company J, which received a request for quote of supplying 400 units per week. Employee must be permitted to perform the task for 17 times. The actual times observed were given below:
Number | Actual time (minutes) |
1 | 2.05 |
2 | 1.92 |
3 | 2.01 |
4 | 1.89 |
5 | 1.77 |
6 | 1.8 |

15 | 1.85 |
16 | 1.85 |
17 | 1.99 |
Performance rating is 115%, fatigue allowance is given as 8%, personal allowance is 6%, and delay allowance is 2%. Workday hour is 7.5 hours and the operators would be paid $12.50 per hour for 8 hours.
