The unit improvement factor for a 60 percent learning curve at 25 units is 0.0933. The first and second timings of a person doing a job are 5 minutes and 3 minutes, respectively. The learning-adjusted time estimate for the unit number 25 is 0.0933 minute.

Question

Quizplus · Accepted Answer

The learning-adjusted time estimate for unit number 25 would be calculated using the learning curve formula, not based on the timings of one person. The formula is: Tn = T1/(n^log2(learning factor)), where Tn is the time for the nth unit, T1 is the time for the first unit, and the learning factor is the percentage of improvement per doubling of units. Plugging in the given values, we get T25 = 5/(25^log2(0.6)) = 1.88 minutes. Therefore, the statement is false.
