What is essential for a successful use case?

A successful use case fundamentally relies on clear requirements because these requirements define what has to be achieved and under what conditions. Clear requirements ensure that all stakeholders have a mutual understanding of the system's intended functionality. They provide a framework for identifying user interactions and system responses, which are crucial for outlining the specific scenarios that the use case will describe. This clarity helps both developers and users avoid miscommunications and ensures that the final product meets user needs effectively.

In contrast, technical jargon and abstract concepts may confuse stakeholders who are not familiar with the specific technology or theory, leading to misunderstandings or misinterpretations of the intended functionality. An unstructured approach lacks the defined methodology necessary for capturing and representing the requirements adequately, which can result in incomplete use cases that fail to convey the necessary information for development. Therefore, clear requirements are vital for ensuring that use cases are precise, understandable, and actionable.
