What artifact of an analyst's work was the result of your tasks? What diagrams or notations did you most often work with?

As a result of an analyst's work, the following artifacts are usually created:

• System requirements (functional and non-functional requirements)
• Business process diagrams (BPMN)
• Use case diagrams
• UML class and sequence diagrams
• User stories and acceptance criteria

UML notations are most commonly used to visualize the structure and behavior of the system, as well as BPMN for describing business processes. For example, use case diagrams help understand user interactions with the system, while sequence diagrams show the order of calls and message exchanges between components.
