Spiral Methodology
nBarry Boehm introduced the Spiral Methodology to "fix"
problems with the Waterfall
Methodology. This is the most commonly used variant of the Waterfall today.
nThe Spiral methodology "peels the onion", progressing
through "layers" of
the development process. A prototype lets users determine if the project is on track, should be sent
back to prior phases, or should be
ended. However, the phases and phase processes
are still linear.
