Standard OO Metrics

Below you see the standard Object oriented metrics in tabular form. According to a NASA Study, they found the following values.

System analyzed	Java	Java	C++
Classes	46	1000	1617
Lines	50,000	300,000	500,000

Quality	"Low"	"High"	"Medium"
CBO	2.48	1.25	2.09
LCOM	447.65	78.34	113.94
RFC	80.39	43.84	28.60
NOC	0.07	0.35	0.39
DIT	0.37	0.97	1.02
WMC	45.7	11.10	23.97

The figures suggest that the higher the CBO and WMC, the lower the quality of the system. This seems to hold for LCOM as well.

Instability-Abstractness

The packages should be placed along the main sequence (marked with green in the figure). The top right corner is often called "the zone of uselessness" due to the package contents high abstractness and low usage. The opposite corner (bottom right) has been named "the zone of pain" due to low degree of abstraction and high usage. Changes in these packages usually imply extensive changes in the rest of the system.
