One important realization on the journey from a BDUF approach to an iterative and agile approach is that design is never done. Designs evolve. The waterfall emphasis has been to unnaturally try to control software physics by imposing requirements freezes and burdensome change control. The process of developing software is part science and part creative. You are applying science toward the invention of something. Design is capturing knowledge both about what the end user need is, and one solution to that need.
