How are the capabilities and qualities of a solution broadly classified?

The categorization of capabilities and qualities of a solution into functional and non-functional requirements is an essential concept in business analysis and requirements management. Functional requirements describe what a system should do; they encompass specific behaviors, processes, and functionalities that the system must accomplish in response to certain inputs or conditions. These requirements directly reflect the functionality that supports the needs of the stakeholders.

Non-functional requirements, on the other hand, address how a system performs a particular function. They encapsulate quality attributes such as performance, security, usability, reliability, and maintainability. Non-functional requirements ensure that the system not only meets its intended functionalities but also operates efficiently under specified conditions, providing an overall satisfactory user experience and fulfilling business objectives.

The clear distinction between these two types of requirements allows business analysts, stakeholders, and development teams to ensure that all necessary aspects of a solution are addressed thoroughly. This dual-classification approach helps in managing expectations and facilitating effective communication throughout the project lifecycle, ensuring that both the operational and qualitative benchmarks of the system are achieved.
