Defect distributions across software components in NASA data

Below are some findings showing the small number of components containing a high density of defects. Note that most components lie below either the red or green lines (average and median respectively), telling us that the majority of components in the data sets shown contain relatively few defects.

KC1 - Ground Control System

PC3 - Flight Software from a current Earth-orbiting satellite

CM1 - Software from a science instrument
