I wouldn't attribute the change to "agile" ... but would attribute the problem to poor design. Subtle difference, but you get the same garbage in agile stuff - just depends on the PM, really.
No, I don't attribute it to being agile, I attribute it to dev being involved near the start of project planning and having input along the way. It just happened that when the company decided on being an agile shop this happened as well. Sorry that was not clear.
