It seems very biased to say the least. A title like that would be ok if it was comparing agile to pre-existing models like waterfall. A valid title for this would have been "new sw development methodology seems to have a much lower failure rate than agile dev. "
ALSO I would like to see the experiment repeated by independent researchers.
"new sw development methodology seems to have a much lower failure rate than agile dev, claims people who stand to make money if new sw development methodology has a lower failure rate. "
