Iterative Methology
	n The Iterative methodology improves on the Spiral methodology. n Each iteration consists of all of the standard Waterfall phases, but each iteration only addresses one subsystem. Further iterations can add resources to the project while ramping up the speed of delivery. n Improves cost control, reduces risk, ensures delivery of (sub)systems, and improves overall flexibility. n Still assumes that the underlying development processes are defined and linear.
