Study Notes
Requirements Engineering
- Establishes the services that the customer requires from a system and the constraints under which it operates and is developed
- Involves iterative activities: requirements elicitation and analysis, requirements validation, and requirements management
Requirements Elicitation and Analysis
- Determines the actual needs of stakeholders
- Identifies the services required by the customer
- Defines the constraints within which the system operates
Requirements Validation
- Checks that the system provides the functions that best support the customer's needs
- Verifies consistency, completeness, and feasibility of requirements
- Ensures requirements can be tested and validated
Requirements Management
- Manages changing requirements during system development and after deployment
- Keeps track of individual requirements and maintains links between dependent requirements
- Establishes a formal process for making change proposals and linking them to system requirements
System Modeling
- Develops models of a system from different perspectives: external, interaction, structural, and behavioral
- Uses graphical notations, typically UML, to represent the system
- Helps analysts understand the system's functionality and communicate with customers
System Modeling Perspectives
- External perspective: models the system's context and environment
- Interaction perspective: models interactions between the system and its environment, or between system components
- Structural perspective: models the system's architecture and components
- Behavioral perspective: models the system's dynamic behavior and response to events
Use Cases
- Developed to support requirements elicitation
- Represents a discrete task involving external interaction with a system
- Each use case involves actors (people or systems) and can be represented diagrammatically or in a detailed textual form
