Passage: Computer systems are complex and often (especially with the recent rise of service-oriented architecture) link multiple traditional systems potentially supplied by different software vendors. To manage this level of complexity, a number of SDLC models or methodologies have been created, such as waterfall, spiral, Agile software development, rapid prototyping, incremental, and synchronize and stabilize.SDLC can be described along a spectrum of agile to iterative to sequential methodologies. Agile methodologies, such as XP and Scrum, focus on lightweight processes which allow for rapid changes (without necessarily following the pattern of SDLC approach) along the development. Iterative methodologies, such as Rational Unified and dynamic systems development, focus on expanding limited project scope and improving by multiple iterative. Sequential or iterative products. Sequential-front-end design, Agile software development, rapid prototyping, incremental, and synchronize and stabilize. SDLC can be described along a spectrum of agile to iterative to sequential methodologies.
