All Rights Reserved CONFIDENIAL  Functional Requirements Functional requirements define what a product, system, or component must do to fulfil its intended purpose. They focus on the tasks the system must perform, not how it should be constructed or look. These requirements serve as the foundation of the design process, aligning the design with user needs and operational goals. A wind turbine must convert wind energy to electrical power between specific wind speeds. Used in automotive braking systems, HVAC systems, and industrial machinery.
