Let’s revisit the learning curve and change some of the assumptions made in the box entitled “How Would You Do That? 1.” Assume that the first bike took 100 hours, the second 85, and the fourth 72. 25. What would the incremental “cost” in hours be for the 16th bike? For the 124th? For the 1,000th? Try to find these numbers using both the formula presented in the feature and the learning curve calculator located at www.jsc.nasa.gov/bu2/learn.html.
