Sensitivity Analysis of the PRICE S and System-3 Software Cost Estimating Models

摘要

The purpose of this thesis effort was to perform an analysis on the PRICE S and System-3 software cost estimating models, in order to determine the domains of consistency for four software development efforts. That is, to determine the sets of inputs for which the two models provide approximately equal estimates. It was necessary to examine the inputs required to run PRICE S, to determine reasonable values for those inputs to describe the four software development efforts of increasing complexity, and to run the PRICE S model to get the estimates for performing those efforts. The PRICE S estimates were used as the baseline for the sensitivity analyses on the System-3 variables. The System-3 variables were examined and compared to the PRICE S variables. There were three types of relationships between the variables. There were some System-3 inputs that had one-to-one correspondence with PRICE S inputs, some that when combined with other System-3 inputs corresponded to a single PRICE S variable, and a few that had no PRICE S equivalent.
