Past criticisms of Function Point Analysis (FPA) have included concerns that it takes too long, it requires too much detail, it is too difficult to implement, and it costs too much. A recent study has shown that an adaptation of the FPA methodology – FP Lite™ – is a reasonable alternative to the detailed FPA method, and in fact, addresses many of the criticisms that have been levied in the past. This paper introduces the FP Lite™ methodology in correlation with two studies designed to statistically understand the accuracy of the FP Lite™ methodology in contrast to the detailed FPA method.
"It's frustrating that there are so many failed software projects when I know from personal experience that it's possible to do so much better - and we can help."
