The group is called ISERN, the International Software Engineering Research Network. It goal is to share experiences on software engineering experimentation, by experimenting, learning, remodeling and further experimenting to build a body of knowledge, based upon empirical evidence.
They have begun replicating experiments, e.g., various forms of replication of the defect-based reading have been performed, and replications of the perspective--based reading experiment are being performed.
Experiments are being run to better understanding the parameters of inspection, ISERN has membership in the U. S., Europe, Asia, and Australia representing both industry and wuknia.
