The use case technique is designed to capture functional requirements and describes how users (or "actors") interact with a system. It explicitly outlines the various scenarios of the interaction, including both preconditions (what must be true before a user can initiate the interaction) and postconditions (what must be true after the interaction is complete). This structured approach helps stakeholders understand the system's behavior in different conditions, as well as the expected outcomes of user interactions.

In contrast, state diagrams primarily focus on the different states an entity can be in and transitions between those states, rather than detailing user interactions within a context. User stories emphasize capturing user needs in a simple and straightforward manner but do not explicitly detail both preconditions and postconditions. Process modeling typically illustrates workflows and processes but may not be designed to incorporate specific user interactions and conditions in the same way that use cases do. Therefore, the use case technique stands out for its comprehensive approach to documenting scenarios involving preconditions and postconditions.
