The iterative model is a particular implementation of a software development life cycle (SDLC) that focuses on an initial, simplified implementation, which then progressively gains more complexity and a broader feature set until the final system is complete. In this article we’ll look at the Waterfall model in a bit more detail, exploring its advantages and disadvantages. This can be achieved by three ways: to supplement traditional processes and documentation, to substitute formal specifications for some traditional documentation, and to substitute formal proofs for some traditional reviews and analyses. SDLC has different methodologies like Agile, Waterfall, Unified model, V Model, Spiral model etc. If by “traditional software development life cycle”, you mean a Big Design Up Front approach where planning is fully done before any code is written, usually the arguments go like this: Argument: You should fully plan your project ahead of time to ensure you don’t waste time coding.
