An Empirical Comparison of Function Points and Web Objects

This paper compares the effectiveness of Function Points and Web Object analysis to estimate the development effort of Web applications. The empirical study is performed on a set of industrial projects carried on in an Italian software company. Starting from original requirements and estimates, carried on using FP analysis, we compute the Web Objects analysis of the same requirements, and compare the results of the two approaches. We also assess the relative effectiveness of FP and WO using post-mortem data about the actual effort taken to develop the studied systems.
