Other Software Development Methodologies..

Software Development  Life Cycle The Systems Development Life Cycle (SDLC) is a conceptual model followed in project developement and management, that describes the various stages involved in an system development processes from an initial feasibility study through maintenance of the completed application. Various SDLC methodologies have been developed to guide the processes involved including the waterfall model (the original SDLC method), rapid application development (RAD), joint application development (JAD), the fountain model and the spiral model. Mostly, several models are combined into some sort of hybrid methodology.
