Over the past forty years, systems engineering has methodically evolved through the Staircase, Early Prototype, Spiral and Rapid Development models. The evolution is characterized by successively deeper penetrations of prototyping concepts into the traditional staircase paradigm. Early prototyping penetrates to the requirements level. The spiral model penetrates to the design level. Rapid Development, the newest innovation, engulfs the entire process resulting in repeated operational deliveries. Each paradigm continues to have its useful niche, but selection of the wrong model for a given task invariably enhances the probability of failure. There is a need for continued education and acceptance of the newer approaches within the technical management and systems engineering communities.
