BMM2001-10 shows clear evidence of learning curve effects for certain technologies where performance deteriorates with early use but improves with increased use (and associated maturity levels). The figure below (Figure 2.5, page 14) shows Owner cost growth with use of design/information technology use across quartiles. The 4th quartile has least use of technology where the 1st quartile has the highest use. As shown in the figure, quartile 3, associated with some use of technology, has the lowest performance and as such is evidence that performance may decrease with early adoption of new technologies. This is consistent with other observations, but was not found in all cases. (BMM2001-10, page 11)
