Spiral Model

The "spiral model" is an iterative model for software development, described by BarryBoehm. Each iteration basically follows the WaterfallModel, but subsequent iterations build upon previous work.

It is called a "spiral" because the common illustrative diagram shows a long string of waterfalls wrapping around a center, emphasizing the aspect of continuous growth and revisiting of previous work. See http://www-db.stanford.edu/~burback/watersluice/node53.html for an example.
