An empirical comparison and characterization of high defect and high complexity modules
2003
Journal of Systems and Software
Preserved Fulltext
We observed that the most complex modules often have an acceptable quality and HD modules are not typically the most complex ones. ...
Our analyses also indicated that the clusters of modules with the highest defects are usually those whose complexity rankings are slightly below the most complex ones. ...
We would like to thank Dave Frame, Tony Nguyen, and others at Nortel Networks for their help throughout this work. ...
