What is the primary purpose of functional requirements?

The primary purpose of functional requirements is to outline the features and capabilities of a solution. These requirements specify what a system, application, or product should be able to do. They serve as a foundation for defining and understanding how the functional components will contribute to achieving business objectives and overall user satisfaction.

Functional requirements focus on the actions that the system must perform, detailing the behavior of the system or product in terms of specific outputs given particular inputs. This can include user interactions, processing requirements, and data handling. By clearly articulating these requirements, stakeholders can ensure that the solution meets their needs and expectations.

In the context of the other options, descriptions of performance under certain conditions relate more to non-functional requirements, which address how the system performs rather than what it does. Identifying potential risks is a strategic activity that falls under risk management, while prioritization of requirements pertains to managing stakeholder needs and ensuring the most critical requirements are addressed first. However, these activities do not define the core purpose of functional requirements, which is centered around detailing the solution's capabilities.
