Preston Smith has written a pragmatic overview from of why Agile works. I particularly liked the reference to Donald Reinertsen’s research that showed:

• Out of hundreds of projects, there is no case in which requirements remained stable throughout design.
• Of more than 200 product developers, fewer than 5% had complete requirements before beginning design.
• On average, design commenced with only 58% of requirements specified.

If requirements are going to change, wouldn’t we be better off acknowledging this and building our processes to accommodate it.
