8. A learning curve shows the decrease in time required for each successive unit completed.

TRUE

There are two ways to think about the improved performance that comes with learning curves: time per unit (as in Exhibit 6.1A) or units of output per time period (as in6.1B). Time per unit shows the decrease in time required for each successive unit. Cumulative average time shows the cumulative average performance times as the total number of units increases.

10. An assumption of learning curves is that the time required to complete a unit will decrease at a decreasing rate as the cumulative number of units completed increases.

TRUE

Learning curve theory is based on three assumptions:

1. The amount of time required to complete a given task or unit of a product will be less each time the task is undertaken.

2. The unit time will decrease at a decreasing rate.

3. The reduction in time will follow a predictable pattern.

13. You time someone completing a single task the first time at 10 minutes, and the second time they do the task it takes 9 minutes. You should use an 80 percent learning curve to estimate the length of time this worker will take to complete this task in the future.

FALSE

The time for the first unit is multiplied by the learning percentage to obtain the time for the second unit. Hence, the time for the second unit divided by the time for the first unit times 100 is the appropriate learning curve and 9/10 × 100 = 90 percent.

TRUE

The time for the first unit is multiplied by the learning percentage to obtain the time for the second unit. Hence, the time for the second unit divided by the time for the first unit times 100 is the appropriate learning curve and 9/10 × 100 = 90 percent.

TRUE

The time for the first unit is multiplied by the learning percentage to obtain the time for the second unit. Hence, the time for the second unit divided by the time for the first unit times 100 is the appropriate learning curve and 108/120 × 100 = 90 percent.
