That Agile Thing

Agile introduction is an interesting problem. One that I have learned to avoid. I am not feeling comfortable standing up to a business owner and saying (paraphrased, of course), "if you will do it my way, your life will be better". At least, not about development methodologies, I have no problem saying that about techniques, design or tools. The reason that I don't feel comfortable saying that is that there are too many issues surrounding agile introduction to talk confidently about the benefits.
