Incremental Model

The Incremental model builds and delivers software in multiple parts instead of all at once. Each part is a working version with its own set of features, and new features keep getting added in the increments that follow, improving the system step by step. It works especially well when requirements are already clear but the team wants to deliver in phases rather than waiting for one final release. The whole idea is to break the project into smaller modules and deliver them one at a time in a systematic way.

How the Incremental Model Works

The Incremental model breaks the whole project into smaller parts or modules. Each module goes through its own mini cycle of design, coding, and testing, and is delivered on its own. Over time, all the modules come together to form the complete software.

When to Use the Incremental Model

This model works well when the project can be broken down into clear, independent modules, and when the team wants to deliver usable parts of the software early instead of waiting for the entire product to be ready.
