There is substantial comment : http://jordanbortz.wordpress.com/2012/07/16/voke-releases-research-report-on-agile-realities/ http://adtmag.com/articles/2012/07/13/report-says-agile-a-scam.aspx

My company has applied Agile patchily, and so this is very important for me as an issue that is live and difficult - there are highly valued employees who passionately advocate it and produce very significant and high quality work while using it, but we are simply unable to use it with some teams and projects, and worse, we have tried in the past in other places in the business and suffered some failures.

I feel we lack real evidence.

The "Hated Slashdot" has a long uniformed discussion on the topic, but I wondered if HN people had specific insights on either killer arguments & studies around using or not using Agile or specific anecdotes that could be used in the debate?
