### Question and Confusion:

The average cycle time of an operation is 0.33 minutes, but one analyst rates the operator at 100% and another analyst rates the same operator at 80%.

As for the assignments, a 24% is granted.

Considering that the difference is only in the rating given by each analyst, the standard time in the first case is (0.33 × 1 × 1.24)= 0.41 Minutes. In the second case, it is (0.33 × 0.80 × 1.24) = 0.33 minutes

The question is why in case 1, where the operator is better rated, the time is greater than in case 2 where the operator is rated with a lower percentage?

This is related to the production capacity per hour, while in case 1 there are 146 units (60÷0.41) and in case 2 there are 181 units (60÷0.33). Shouldn’t it be that with a rating of 100% the production capacity be higher than with an 80% rating. Can you explain the mathematical logic of this case to me?

### Answer to the first question:

The standard time calculation method from the average cycle time shown above is correct. Also, the hourly production capacity of the operators is correct in the above query.One needs to understand the definition of Standard Time. It is the time a 100% performing operator would take to complete an operation.

In the second case, the average cycle time is 0.33 minutes, and with an 80% rating, you are getting Basic time = (0.33 X 0.80) = 0.264 minutes.

I have answered a similar question in the past. Please check that answer as well.

### Capacity Calculation

**hourly capacity**(based on standard time) in the above query is correct.

**potential production capacity**or

**Hourly production target**at 100% Standard Time.
