iterative development - Computer Definition
A discipline for developing systems based on producing deliverables often. Each iteration, consisting of requirements, analysis & design, implementation and testing, results in the release of an executable subset of the final product, which grows incrementally from iteration to iteration to become the final system. An example of iterative development is the Spiral Model introduced in 1988 by Professor Barry Boehme at the University of Southern California. See agile software development.
