kasutusstsenaarium

A kasutusstsenaarium, or use case, is a description of how a user will interact with a system to achieve a specific goal. It outlines the steps involved in the interaction, from the user's perspective and the system's response. Kasutusstsenaariumid are essential tools in software development and system design, helping to define the functional requirements of a system and ensure it meets user needs.

Each kasutusstsenaarium typically includes a title, a brief description, actors (the users or other systems interacting with the system), preconditions (what must be true before the scenario can begin), the main success scenario (the typical sequence of steps leading to successful completion), and alternative flows and exceptions (variations or error conditions). They are often used to guide the development process, test the system's functionality, and communicate system behavior to stakeholders.

The primary purpose of a kasutusstsenaarium is to capture the "what" and "how" of user interaction. They help designers and developers understand the user's perspective and ensure that the system is intuitive and effective. By detailing the interactions, kasutusstsenaariumid can uncover potential usability issues and misunderstandings early in the development lifecycle, reducing the cost and effort of fixing problems later. They serve as a bridge between user requirements and system implementation, ensuring that the final product aligns with its intended purpose.
