Use Case Analysis in System Development

These flashcards cover key concepts from the chapter on Use Case Analysis as part of the software development life cycle.

Requirements Elicitation Techniques

Methods used to gather user requirements, such as interviews, workshops, and questionnaires.

Use Case

A description of how a system interacts with its environment to accomplish a task, focusing on user interactions.

Actor

An entity (person, system, or device) that interacts with the system to achieve a goal.

Trigger

An event that initiates a use case or a specific action within the system.

Preconditions

Conditions that must be true before a use case can begin.

Postconditions

Conditions that must be true after a use case has completed.

Normal Course

The sequence of steps that outlines the expected interaction between the user and the system under typical conditions.

Alternative Courses

Paths within a use case that describe different scenarios or decisions that might occur during the primary workflow.

Exceptions

Error conditions or unusual events that can occur during the execution of a use case.

Functional Requirements

Specifications that describe what the system should do, derived from use cases.

Iterative Process

A repetitive approach where the development is refined through repeated cycles (iterations) to improve quality and detail of the product.

JAD Sessions

Joint Application Development sessions where stakeholders come together to discuss and refine system requirements.
