"Agile solves problems and introduces others!"It was clear that he has a negative attitude towards "Agile"; may be he is talking about some bad failure patterns of Agile implementation, like those I mentioned in this blog item.
However, I would affirm that the amount of problems that Agile solves are far way bigger than the ones introduced.
I also forgot to ask him: What about CMMI-based process improvement, specially those following waterfall or phased development, does it really solve any problems? or just introduces others :)
