Methodologies can be defined across a spectrum, from iterative to pure waterfall. Iterative methodologies are
defined by short release cycles in which the change initiative is delivered piecemeal with small impacts occurring
over time. At the other end of the spectrum is a more traditional development process, the waterfall model,
in which the entire change initiative is designed and built in order to be released all at once. The extremes on
each side of the spectrum hold advantages and disadvantages, and many options exist between the two. In
any case, a well-defined methodology with a project team educated in the methodology’s different phases
helps ensure that the project will be successful from the technical standpoint.
