"Another is an "early and striking example of a major IID success is the
very heart of NASA's space shuttle software--the primary avionics
software system, which FSD built from 1977 to 1980. The team applied IID
in a series of 17 iterations over 31 months, averaging around eight
weeks per iteration. Their motivation for avoiding the waterfall life
cycle was that the shuttle program's requirements changed during the
software development process"."
