Fig. 9.1.5 Classical systems development.In classical SDLC processing, the first step is to gather requirements. In classical SDLC,
the intent is to gather all requirements before the next step of development occurs. This
approach is sometimes called the “waterfall” approach because of the need to gather all
requirements before engaging in the next step of development.
But heuristic processing is fundamentally different than the class SDLC. In heuristic
processing, you start with some requirements. You build a system to analyze those
