Abstract

Applying metrics to software is a way to measuring and improving software qual- ity. Many metrics apply to software implementations (code), so they cannot be used early in the life cycle. We survey eight modularity and structural complexity metrics applicable to software designs, and summarize the results of empirical val- idation studies when they are available. We present a data model from which all these metrics can be computed. Aspects of each metric require further study and refinement. However, using some of them during design may still be beneficial. Introduction The 4Thought project [14], which aims to develop generic tools to assist software designers, views a design as a database of information about software components and relationships among them. As part of this effort, we h
