View Digital Edition. We aim to alleviate such concerns by using a framework based on software metrics to accurately quantify factors contributing to the overall quality of a COTS-Based System CBS and guide decisions regarding quality and risk management.

Article :. We examine the repositories for 25 software systems ranging from 3, to , source lines from this software environment. We apply nonparametric statistical models to compare numerous development variables across the 2, software modules in the systems. We identify two categories of factors that characterize successful reuse-based software development of large-scale systems: module design factors and module implementation factors.
