Measuring stability of object-oriented software architectures

What is it about?

Architectural stability is an important attribute for software systems. Several metrics are proposed to measure this attribute but they mainly measure changes in cross-components structural relationships and not cross-components communication. This paper develops a new architectural stability metric (ASM) that measures inter-package calls. The new metric is theoretically and empirically validated.

Why is it important?

The new metric addressed one of limitation in the existing metrics. It also works at early stage in the develpomnet life cycle i.e., architectural design level.
