Käyttövaatimuksiin

Käyttövaatimuksiin, often translated as "functional requirements," refers to the specific behaviors and functions a system must perform. These are the core capabilities that the system will offer to its users or other systems. They describe what the system *does*, rather than how it does it. For example, a functional requirement for an e-commerce website might be "The system shall allow users to add items to a shopping cart."

These requirements are crucial for defining the scope of a project and ensuring that the final product meets the intended needs. They are typically derived from stakeholder needs and business objectives. Clear and unambiguous functional requirements help guide the design, development, and testing phases of a software project. They serve as a contract between the developers and the stakeholders, outlining the expected outcomes.

Functional requirements can be categorized in various ways, such as by user roles, system features, or business processes. Examples include data manipulation, calculations, business processes, and user interactions. Well-defined käyttövaatimuksiin are essential for successful software development, as they provide a foundation for all subsequent activities. They are often documented in a requirements specification document.
