Metrics: Do metrics matter?

Metrics That Matter

Within NASA, there is an increasing awareness that software is of growing importance to the success of missions. Much data has been collected, and many theories have been advanced on how to reduce or eliminate errors in code. However, learning requires experience. This article documents a new NASA initiative to build a centralized repository of software defect data; in particular, it documents ...

Metrics that Matter

Metrics, Do They Really Help?

Maturing a well designed framework requires a set of software metrics to steer the iterative development process. Based on a case study of the VisualWorks/Smalltalk framework for user-interface building, we conclude that today’s size and inheritance metrics are not reliable to detect problems but are useful in measuring stability. We expect that this work will contribute to the application of m...

On C3-Like Finsler Metrics

In this paper, we study the class of of C3-like Finsler metrics which contains the class of semi-C-reducible Finsler metric. We find a condition on C3-like metrics under which the notions of Landsberg curvature and mean Landsberg curvature are equivalent.

Generalized Douglas-Weyl Finsler Metrics

In this paper, we study generalized Douglas-Weyl Finsler metrics. We find some conditions under which the class of generalized Douglas-Weyl (&alpha, &beta)-metric with vanishing S-curvature reduce to the class of Berwald metrics.
