toiminnallisuuskriteereitä

Toiminnallisuuskriteerit, or functional requirements, are a crucial part of system development and project management. They describe the specific behaviors or functions that a system must perform. In essence, they define what the system should do. These criteria are not about how the system will be built, but rather about the tasks it must accomplish for its users.

Functional requirements are typically derived from user needs and business objectives. They provide a clear and unambiguous specification that guides the design, development, and testing phases. For example, in a banking system, a functional requirement might be "The system shall allow users to transfer funds between their accounts." This clearly states a specific action the system must support.

To be effective, functional requirements should be detailed, measurable, and testable. They serve as a contract between the client and the development team, ensuring that everyone has a shared understanding of the system's intended functionality. Well-defined toiminnallisuuskriteerit help prevent scope creep and reduce the likelihood of misunderstandings during the project lifecycle. They are a cornerstone of successful software and system engineering.
