Types of Waterfall Methodologies:
Classic Waterfall: This is the original and most basic form of the Waterfall methodology. It involves a strict sequential progression through each phase, with no overlapping or backtracking.
Iterative Waterfall: This modified Waterfall approach introduces iterations, allowing for feedback and adjustments within each phase before moving to the next. This can help to mitigate risks and improve project outcomes.
Rapid Application Development (RAD) Waterfall: RAD is an accelerated version of the Waterfall methodology, emphasizing rapid prototyping, continuous user feedback, and parallel development of phases. It aims to deliver working software quickly and efficiently.
