Iterative Software Development

Iterative Software Development

iterative development

Iterative development is a way of breaking down the software development of a large form into smaller chunks. In iterative development,  feature code is produced, generated and tested in reconstructed periods. With each iteration, additional features can be designed, developed and tested until there is a fully functional software application available to be disposed to customers.

Iterative/ Incremental

Incremental development slices the system functionality into increments (pieces). In each increment, a slice of functionality is delivered through cross-discipline work, from the requirements to the deployment. The unified process groups increments/iterations into phases: beginning, elaboration, construction, and transition.

Each of the phases may be divided into one or more iterations, which are usually time-boxed rather than feature-boxed. Architects and investigators work one iteration ahead of developers and testers to keep their work-product backlog full.

Incremental – adding new functionality in small chunks

Iterative – performing frequently, adding new functionality in a repeated or cyclic manner,

In incremental development-system functionality is sliced into increments (divisions), whereby in each increment, a slice of functionality is delivered.

In incremental development, different parts of the system are developed at various times or rates and are combined based on their completion
