Iterative model

The iterative model breaks a project into small modules that can be delivered incrementally. A working version is produced in the first module, with each subsequent release adding additional functionality until the full system is complete. It allows for quick releases during development and makes it easier to develop and test in smaller iterations while incorporating customer feedback at each stage. However, it requires more resources than traditional models and skilled management to avoid increased costs over time.

- 2. • Also called Incremental Model • Project is break into small modules which can be delivered • A working version of software is produced during the first module. • Each subsequent release of the module adds functionality to the previous release. The process continues till the complete system is achieved. • Model very successfully when working with new technology • More than one iteration can be going at the same time http://appium-selenium.com/

- 4. •Quick software is released during early phases of Software life cycle •Less costly to change requirements as compared to other models •Easier to develop and test when iterations are small •Customer can give his feedback quickly •More than one iteration can be going parallel at same time Advantages of Iterative Model http://appium-selenium.com/
