Kasutusülesanded

Kasutusülesanded, often translated as "use cases," are a fundamental concept in software engineering and requirements analysis. They describe how a user interacts with a system to achieve a specific goal. A kasutusülesanne typically outlines a sequence of actions performed by an actor (a user or another system) and the system's responses to those actions.

The primary purpose of a kasutusülesanne is to capture functional requirements from the user's perspective. They help clarify what the system should do and how it should behave in different scenarios. By focusing on user goals, kasutusülesanded ensure that the developed system meets the needs of its intended audience.

A well-defined kasutusülesanne usually includes a name, a brief description, the actor(s) involved, pre-conditions, post-conditions, and a main success scenario. It can also include alternative flows and exception conditions, detailing what happens when things don't go as planned. This comprehensive approach aids in identifying potential issues and edge cases early in the development process.

Kasutusülesanded are valuable for communication among stakeholders, including developers, testers, designers, and clients. They provide a common understanding of system functionality, reducing ambiguity and facilitating agreement on project scope. They serve as a basis for test case creation and can guide the design of the user interface. In essence, kasutusülesanded bridge the gap between user needs and system implementation.
