Which process model is also called the classic life cycle model?

Explanation

Pressman introduces the waterfall model under the heading "the classic life cycle", because it was the first published process model and it prescribes the systematic, sequential flow of communication, planning, modelling, construction and deployment that every later model reacted against. The RAD model is a compressed, component-based variant aimed at very short development cycles. The prototyping model builds a throwaway mock-up to clarify requirements. The incremental model delivers the product in a series of releases, each adding function. Only the waterfall carries the name classic life cycle.
