Abstract

This paper investigates the nature of the relationship between software product size measured by Common Software Measurement International Consortium (COSMIC) Function Points and the development effort. We investigated which of the numerical and categorical cost drivers explain the variation in the development effort by performing step wise Analysis of Variance (ANOVA), Analysis of Co-Variance (ANCOVA) and Linear Regression Analysis. For the statistical analyses, we utilized the International Software Benchmarking Standards Group (ISBSG) Dataset Release 10. In this paper, we discuss the results we obtained and the significance of the results for the software organizations who would like to improve their effort estimation processes.
