In this tutorial we are going to learn about the Software Development Life Cycle, which includes the following topics:- . Iterative model  . When to use Iterative Model . Advantages/Disadvantages of Iterative model . Spiral model . When to use Spiral Model . Advantages/Disadvantages of Spiral model The Fifth mode l of SDLC is "Iterative Model" . This is the Fifth model of SDLC after Spiral model. This model is also called as Incremental model .Let us discuss about the Iterative model in Detail :- Iterative model :- Software development with the help of this model leads to a development process in iterations. Incremental development divides the system functionality onto portions basically called increments.It is the process of develop the software in increments. At first, the process is developed at very small scale by following all steps into consideration.These process groups Iteration into phases. i.e. inception, elaboration,construction

Software development process, commonly known as Software development life cycle, is a process used by the software industry for designing, development and testing high quality software. The Aim of Software development life cycle(SDLC) is to produce high-quality software that meets i.e. exceeds customer expectations, and also reaching completion within the cost estimates and within time. The framework of SDLC is to define tasks performed at each step in the software development process. In this tutorial we are going to learn about the Software Development Life Cycle, which includes the following topics, What is SDLC? Stages of SDLC Models of SDLC Conclusion What is SDLC? The process followed by software project within the software organization is called software development life cycle. Basically its consists of detailed plan which describe how to develop, maintain a software, replace and alter or enhance specific software . SDLC “Life cycle
