Feature-Driven Development (FDD)

Feature-Driven Development (FDD) is an iterative and incremental software development methodology that organizes the entire process around the delivery of client-valued features. It focuses on a short, iterative development cycle where features are designed, built, and tested in a systematic way.

Example: A team is building a new e-commerce application. Using FDD, the project manager identifies key features, such as "a customer can log in" or "a customer can view their order history." Each feature is then developed and tested as a complete unit. A developer would work on the login feature from design to implementation, and once it's complete, it's immediately tested to ensure it works as a standalone, functional piece of the application.
