Resolve the unresolved challenge of validating software metrics

Establish scientifically sound methods for validating software metrics so that their measurements reliably represent software-quality constructs.

Background

The paper situates software-metric validation within a broader methodological problem: many metrics are proposed, implemented, and used without sufficient theoretical or empirical evidence that they measure their intended constructs. The authors emphasize that correlation with other metrics is not equivalent to validation and that valid measurement requires a stronger measurement-theoretic foundation.

This problem is included because the paper explicitly characterizes metric validation as unresolved and identifies addressing it as necessary for reliable software-quality measurement. The authors’ factor-analysis framework is presented as one contribution toward this broader challenge, rather than as a complete solution to validation in all software-metric contexts.
