  • Iterative Model (Incremental Model) in SDLC

    • In Iterative Model ,the process of defining requirements, designing, building and testing a system, completed as a series of shorter development cycles.
    • Software development process where requirements are divided into several stand-alone software development modules.
    • Produces and delivers the working component at each increment of the project.
    • There are few examples of iterative Models are : prototyping, Rapid Application Development (RAD), Rational Unified Process (RUP) and agile development models.
    Iterative Model in SDLC

    Phases of incremental Model

     Requirement analysis

        • Product analysis expertise identifies the functional requirements and non-functional requirements.
        • Product analysis expertise communicates with the customer and note down all the requirements of the customer.

     Design & Development

        • The design phase defines how the system will accomplish what was defined in the Requirement analysis phase.
        • In the design phase, all components of the system are defined.


        • Coding is done for developing software.
        • Design, which is finalised in designing phase, is now implemented practically and the coding is completed.
        • Programs are coded in small units to implement the working product


        • The goal of the testing phase is to find errors, which means that a good testing strategy is the one that finds most errors.
        • Examines the performance of each existing function as well as additional functionality.

     Advantages of Iterative Model

        • Errors are easy to detect.
        • Easier to test and debug during a smaller iteration
        • More Flexible, hence less costly to change scope and requirements.
        • Lowers initial delivery cost.
        • Easy to manage risk because it is managed through iteration.

     Disadvantages of Iterative Model

        • Needs good planning and design.
        • Total cost is higher than waterfall.
        • Needs well-defined module interfaces.

     When to use the Incremental model?

        • This model can be used when the requirements of the whole system are clearly defined and understood.
        • There is a need to get a product to the market early.
        • Resources with required skill sets are not available
        • There are some high-risk features and goals.
