The article focuses on the percentage of software projects failure rates. The author has seen software failure trumpeted from so many academic research papers that he had to quit counting. However, if one closely examines the citations they use to support the claims of crisis, over and over again the citations boil down to one primary source, the Standish Chaos Reports. Those academic researchers who quote those original 1994 figures have ignored the fact that Standish has updated the Chaos Report periodically. The 2000 report, for example, saw a drop in cancelled projects to 23 percent, a small drop in challenged projects to 49 percent, and a corresponding increase in successful projects to 28 percent. Looking at other research studies of software failures, they discovered something interesting. Whereas Standish reported those 189 percent overruns, three other studies reported a consistent 33 to 34 percent cost overrun. Clearly, something was at best inconsistent between what Standish was doing and what the other three studies had learned.
