Iterative Model

Development in this model begins by specifying and implementing only part of the system which is further reviewed to identify additional requirements. Also, the iterative process begins with a basic implementation of a specific set of system specifications in the iterative model, which iteratively improves the developing iterations until the entire system is implemented and ready for deployment.

Every Iterative model is built over a given and defined period, which is called iteration. The method is repetitive and allows for the development of new product versions for each cycle. Each implementation involves the creation of a new system component, and then this component is applied to the previously defined functional.

Phases of iterative model

  • Requirements Phase
  • Design Phase
  • Implementation and Test
  • Review Phase

Advantages

Some functions can be built quickly at the beginning of the development lifecycle,

  • The parallel development can be implemented
  • We can map the faults in the early stages
  • Due to shorter iteration testing is simple
  • It is easier to manage the risks as high-risk activities are completed first
  • Problems and the risks identified within one iteration can be prevented in the next Flexible sprints

Disadvantages

  • The iterative model needs more resources than the waterfall model
  • Problems with architecture or design may occur because not all requirements are foreseen during the short planning phase
  • This model is not suitable for small projects
  • The risks may not be fully defined even at the final stage of the project Risk analysis needed
