On this site, Chillarege shares a number of technical articles. We do this as a service to the community. Over the years, we have noticed that there seems to be a significant interest in aspects of software engineering measurement and analysis - as witnessed by the large number of hits and downloads.
We have a fairly complete list of the classical articles on Orthogonal Defect Classification (ODC). We have added a number of Tech Briefs, which are more user friendly articles on specific sub-topics that often get overlooked in the professional white papers, or refereed publications.
Training material on ODC is available only for clients, and needs special access.
