Iterative Enhancement Model
This model was developed to remove disadvantages of waterfall model. In this model, phases of software development remain the same however the construction and delivery is done in iterative mode. In first iteration, a less capable productis developed and delivered for use. This product satisfies onlya subset of the requirements. In subsequent iteration, a product with incremental features is developed.
Every iteration comprises all phases of the waterfall model. Completeproduct is divided into releases and developer delivers the product release by release. Figure below depicts Iterative Enhancement Model.
