You have just timed a person doing a job a few times. The first time it took the person 25 minutes, the second time it took 20 minutes, and the third time it took 17.55 minutes. Which learning curve unit improvement factor should you use?
A) 25 percent
B) 75 percent
C) 80 percent
D) 85 percent
E) 90 percent

The learning curve unit improvement factor is calculated based on the time it takes to complete a task after each iteration. The improvement from 25 minutes to 20 minutes is a 20% reduction (since 20 is 80% of 25), and from 20 minutes to 17.55 minutes is also approximately a 12.25% reduction, which is close to an 80% learning curve (since 17.55 is approximately 87.75% of 20, but the consistent factor applied from the start is what's considered). Therefore, the closest and most consistent improvement factor across these iterations is 80%, indicating that each time the task is performed, it takes roughly 80% of the time it took on the previous iteration.
