Tapauksenkäyttö

Tapauksenkäyttö, meaning "case usage" or "scenario usage" in Finnish, is a concept used in software development and requirements engineering. It refers to a detailed description of how a user or system interacts with a software product to achieve a specific goal. Tapauksenkäyttö is often synonymous with the English term "use case."

The purpose of tapauksenkäyttö is to capture functional requirements from the perspective of the user. Each tapauksenkäyttö describes a sequence of actions that a user performs to achieve a particular outcome. This includes identifying the actor (the user or external system), the goal, and the steps involved. It also outlines preconditions, postconditions, and potential alternative flows or error conditions.

By creating tapauksenkäyttö, development teams gain a clear understanding of what the system needs to do and how it will be used in real-world scenarios. This helps in designing user-friendly interfaces, defining system behavior, and ensuring that the final product meets the needs of its intended users. Tapauksenkäyttö serve as a valuable communication tool between stakeholders, developers, and testers throughout the software development lifecycle. They are a fundamental part of many agile methodologies and traditional software engineering approaches.
