Assessing the changeability of two Object-Oriented Design Alternatives -a Controlled Experiment

摘要

An important motivation for the object-oriented paradigm is to improve the changeability of the software, thereby reducing lifetime development costs. This paper describes the results of controlled experiments assessing the changeability of a given responsibility-driven (RD) design versus an alternative control-oriented "mainframe" (MF) design. According to Coad and Yourdon's OO design quality prin- ciples, the RD design represents a "good" design.
