Functional requirements refer to what aspect of a solution?

Functional requirements specifically describe the tasks or behaviors that a system must be able to perform. They detail what a system should do, outlining the specific functionalities that the stakeholders expect from the solution. This includes actions that a system can take, inputs that must be captured, outputs that must be generated, and interactions that users will have with the system.

For example, in a data analytics software, functional requirements might include the ability to generate reports, perform data visualizations, and integrate with other data sources. These requirements focus on the operations, features, and capabilities that are necessary for the system to meet its intended purpose and fulfill user needs effectively.

In contrast, other options address aspects that are not directly related to the functionalities of the solution itself, such as quality attributes, performance metrics, or financial considerations. While these elements are important for evaluating overall project success and feasibility, they don't define what the system is specifically designed to do.
