Functional Requirements

Functional requirements define what a system is supposed to do. They describe the behaviors, functions, and features the system must support, and are critical for the development and testing phases of the product lifecycle.

Example

For the development of Microsoft Word, functional requirements would include the ability to create and edit text documents, format text, insert images, and save documents in various file formats. These requirements guide the development team in creating a product that meets user needs.
