LEARNING-CURVE TABLES: VOLUME I. 55-69 PERCENT SLOPES,

Abstract : The report comprises volume 1 of a three volume series of learning-curve data, including unit curve midpoints for plotting first-lot quantities. Accurate representation of the first-lot quantity is important, because misplacing this point could lead to incorrect conclusions about the cost-quantity relationship. In the past, unit curve midpoints were estimated by various approximation methods because the calculations to obtain tables of true midpoints were complex and laborious. Now, through use of high-speed computers, such calculations can be made quickly and inexpensively. Accordingly, these volumes were prepared to assemble all the information a cost analyst is likely to need in using or plotting learning-curve data. This material was prepared for use in all Air Force cost analysis activities and should also be useful to the other services and the aerospace industry. (Author)
